On the first (lower) layer it hides all platform +dependent implementation details (allocation and locking) when dealing with +shared memory segments and on the second (higher) layer it provides a +high-level \fImalloc\fR\|(3)\-style API for a convenient and well known way to work +with data-structures inside those shared memory segments. +.PP +The abbreviation \fBMM\fR is historically and originally comes from the phrase +``\fImemory mapped\fR'\*(R' as used by the POSIX.1 \fImmap\fR\|(2) function. Because this +facility is internally used by this library on most platforms to create the +shared memory segments. +.Sh "\s-1LIBRARY\s0 \s-1STRUCTURE\s0" +This library is structured into three main APIs which are internally based on +each other: +.Ip "\fBGlobal Malloc-Replacement \s-1API\s0\fR" 4 +This is the most high-level \s-1API\s0 which directly can be used as replacement \s-1API\s0 +for the \s-1POSIX\s0.1 memory allocation \s-1API\s0 (\fImalloc\fR\|(2) and friends). This is +useful when converting \fIheap\fR based data structures to \fIshared memory\fR +based data structures without the need to change the code dramatically. All +which is needed is to prefix the \s-1POSIX\s0.1 memory allocation functions with +\f(CWMM_\fR, i.e. \f(CWmalloc\fR becomes \f(CWMM_malloc\fR, \f(CWstrdup\fR becomes \f(CWMM_strdup\fR, +etc. This \s-1API\s0 internally uses just a global \f(CWMM*\fR pool for calling the +corresponding functions (with prefix \f(CWmm_\fR) of the \fIStandard Malloc-Style +\s-1API\s0\fR. +.Ip "\fBStandard Malloc-Style \s-1API\s0\fR" 4 +This is the standard high-level memory allocation \s-1API\s0. It's interface is +similar to the \fIGlobal Malloc-Replacement \s-1API\s0\fR but it uses an explicit \f(CWMM*\fR +pool to operate on. That's why every function of this \s-1API\s0 has an argument of +type \f(CWMM*\fR as the first argument. This \s-1API\s0 provides a comfortable way to +work with small dynamically allocated shared memory chunks inside large +statically allocated shared memory segments. It's internally based on the +\fILow-Level Shared Memory \s-1API\s0\fR for creating the underlaying shared memory +segment. +.Ip "\fBLow-Level Shared Memory \s-1API\s0\fR" 4 +This is the basis of the whole \fB\s-1MM\s0\fR library. It provides low-level functions +for creating shared memory segments with mutual exclusion (in short: \fImutex\fR) +capabilities in a portable way. Internally the shared memory and mutex +facility is implemented in various platform-dependent ways. A list of +implementation variants follows under the next topic. +.Sh "\s-1SHARED\s0 \s-1MEMORY\s0 \s-1IMPLEMENTATION\s0" +Internally the shared memory facility is implemented in various +platform-dependent variants. Each has it's own advantages and disadvantages +(in addition to the fact that some variants aren't available at all on some +platforms). The \s-1MM\s0 libraries configuration procedure tried hard to make a good +decision. The implemented variants are now given for overview and background +reasons with their advantages and disadvantages and in an ascending order, +i.e. the \s-1MM\s0 configuration mechanism chooses the last available one in the list +as the preferred variant. +.Ip "Classical mmap(2) on temporary file (\s-1MMFILE\s0)" 4 +\fIAdvantage:\fR maximum portable. +\fIDisadvantage:\fR needs a temporary file on the filesystem +.Ip "mmap(2) via \s-1POSIX\s0.1 shm_open(3) on temporary file (\s-1MMPOSX\s0)" 4 +\fIAdvantage:\fR standardized by \s-1POSIX\s0.1 and theoretically portable. +\fIDisadvantage:\fR needs a temporary file on the filesystem and is +is usually not available on existing Unix platform. +.Ip "\s-1SVR4-\s0style mmap(2) on \f(CW/dev/zero\fR device (\s-1MMZERO\s0)" 4 +\fIAdvantage:\fR widely available on mostly portable on \s-1SVR4\s0 platforms. +\fIDisadvantage:\fR needs the \f(CW/dev/zero/\fR device and an \fImmap\fR\|(2) +which supports memory mapping through it. +.Ip "4.4BSD\-style mmap(2) via \f(CWMAP_ANON\fR facility (\s-1MMANON\s0)" 4 +\fIAdvantage:\fR doesn't need a temporary file or external device +\fIDisadvantage:\fR usually only available on \s-1BSD\s0 platforms and derivatives. +.Ip "SysV \s-1IPC\s0 shmget(2) (\s-1IPCSHM\s0)" 4 +\fIAdvantage:\fR doesn't need a temporary file or external device +\fIDisadvantage:\fR although available on mostly all modern Unix platforms it has +hard restrictions like the maximum size of a single shared memory segment (can +be as small as 100KB, but depends on the platform). +.Sh "\s-1LOCKING\s0 \s-1IMPLEMENTATION\s0" +As for the shared memory facility, internally the locking facility is +implemented in various platform-dependent variants. A short overview of +implemented variants is given: +.Ip "4.2BSD\-style flock(2) on temporary file (\s-1FLOCK\s0)" 4 +\fIAdvantage:\fR exists on a lot of platforms, especially on older Unix +derivates. \fIDisadvantage:\fR needs a temporary file on the filesystem and has +to reopen filedescriptors to it in \fIeach\fR\|(!) \fIfork\fR\|(2)ed child process. +.Ip "SysV \s-1IPC\s0 semget(2) (\s-1IPCSEM\s0)" 4 +\fIAdvantage:\fR exists on a lot of platforms and doesn't need a temporary file. +\fIDisadvantage:\fR an unmeant termination of the application leads to a +semaphore leak because the facility doesn't allow an \*(L"remove in advance\*(R" trick +(as the \s-1IPC\s0 shared memory facility does!) for safe cleanups. +.Ip "\s-1SVR4-\s0style fcntl(2) on temporary file (\s-1FCNTL\s0)" 4 +\fIAdvantage:\fR exists on a lot of platforms and is also the most powerful +variant (although not always the fastest one). \fIDisadvantage:\fR needs a +temporary file. +.Sh "\s-1MEMORY\s0 \s-1ALLOCATION\s0 \s-1STRATEGY\s0" +The memory allocation strategy the \fIStandard Malloc-Style \s-1API\s0\fR functions use +internally is the following: +.Ip "\fBAllocation\fR" 4 +When a chunk of memory has to be allocated, the internal list of free chunks +is searched for a minimal-sized chunk which is larger or equal than the size +of the to be allocated chunk (some sort of a \fIbest fit algorithm\fR). +.Sp +When a chunk is found which matches this best-fit criteria, but is still a lot +larger than the requested size, it is split into two chunks: One with exactly +the requested size (which is the resulting chunk) and one with the remaining +size (which is immediately re-inserted into the list of free chunks). +.Sp +When no fitting chunk is found at all in the list of free chunks, a new one is +created from the spare area of the shared memory segment until the segment is +full (in which case an \fIout of memory\fR error occurs). +.Ip "\fBDeallocation\fR" 4 +When a chunk of memory has to be deallocated, it is inserted in sorted manner +into the internal list of free chunks. The insertion operation automatically +merges the chunk with a previous and/or next free chunk when possible, i.e. +the free chunks stay physically seamless (one after another) in memory, to +automatically form larger free chunks out of smaller ones. +.Sp +This way the shared memory segment is automatically defragmented when memory +is deallocated. +.PP +This strategy reduces memory waste and fragmentation caused by small and +frequent allocations and deallocations to a minimum. +.PP +The internal implementation of the list of free chunks is not specially +optimized (for instance by using binary search trees or even splay trees, +etc.), because it's assumed that the total amount of entries in the list of +free chunks is always small (caused both by the fact that shared memory +segments are usually a lot smaller than heaps and the fact that we always +defragment by merging the free chunks when possible). +.SH "API FUNCTIONS" +In the following all API functions are described in detail. +The order directly follows the one in the SYNOPSIS. +.Sh "Global Malloc-Replacement \s-1API\s0" +.Ip "int \fBMM_create\fR(size_t \fIsize\fR, const char *\fIfile\fR);" 4 +This initialized the global shared memory pool with \fIsize\fR and \fIfile\fR and +has be called \fIbefore\fR any \fIfork\fR\|(2) operations are performed by the +application. +.Ip "int \fBMM_permission\fR(mode_t \fImode\fR, uid_t \fIowner\fR, gid_t \fIgroup\fR);" 4 +This sets the filesystem \fImode\fR, \fIowner\fR and \fIgroup\fR for the global shared +memory pool (has effects only when the underlaying shared memory segment +implementation is actually based on external auxiliary files).

Here \fIfile\fR is a filesystem path to a +file which need not to exist (and perhaps is never created because this +depends on the platform and chosen shared memory and mutex implementation). +The return value is a pointer to an \f(CWMM\fR structure which should be treated as +opaque by the application. It describes the internals of the created shared +memory pool. In case of an error \f(CWNULL\fR is returned.

The result is undefined +when \fIptr\fR was not previously allocated with \fImm_malloc\fR\|(3). +.Ip "size_t \fBmm_maxsize\fR(void);" 4 +This function returns the maximum size which is allowed as the first argument +to the \fImm_create\fR\|(3) function. +.Ip "size_t \fBmm_available\fR(\s-1MM\s0 *\fImm\fR);" 4 +Returns the amount in bytes of still available (free) memory in the +shared memory pool \fImm\fR. +.Ip "char *\fBmm_error\fR(void);" 4 +Returns the last error message which occurred inside the \fB\s-1MM\s0\fR library. +.Ip "void \fBmm_display_info\fR(\s-1MM\s0 *\fImm\fR);" 4 +This is debugging function which displays a summary page for the shared memory +pool \fImm\fR describing various internal sizes and counters. +.Sh "Low-Level Shared Memory \s-1API\s0" +.Ip "void *\fBmm_core_create\fR(size_t \fIsize\fR, const char *\fIfile\fR);" 4 +This creates a shared memory area which is at least \fIsize\fR bytes in size with +the help of \fIfile\fR. The value \fIsize\fR has to be greater than 0 and less or +equal the value returned by \fImm_core_maxsegsize\fR\|(3). Here \fIfile\fR is a +filesystem path to a file which need not to exist (and perhaps is never +created because this depends on the platform and chosen shared memory and +mutex implementation). The return value is either a (virtual memory word +aligned) pointer to the shared memory segment or \f(CWNULL\fR in case of an error. +The application is guaranteed to be able to access the shared memory segment +from byte 0 to byte \fIsize\fR\-1 starting at the returned address. +.Ip "int \fBmm_core_permission\fR(void *\fIcore\fR, mode_t \fImode\fR, uid_t \fIowner\fR, gid_t \fIgroup\fR);" 4 +This sets the filesystem \fImode\fR, \fIowner\fR and \fIgroup\fR for the shared memory +segment \fIcode\fR (has effects only when the underlaying shared memory segment +implementation is actually based on external auxiliary files). The arguments +are directly passed through to \fIchmod\fR\|(2) and \fIchown\fR\|(2). +.Ip "void \fBmm_core_delete\fR(void *\fIcore\fR);" 4 +This deletes a shared memory segment \fIcore\fR (as previously returned by a +\fImm_core_create\fR\|(3) call). After this operation, accessing the segment starting +at \fIcore\fR is no longer allowed and will usually lead to a segmentation fault. +.Ip "int \fBmm_core_lock\fR(const void *\fIcore\fR, mm_lock_mode \fImode\fR);" 4 +This function acquires an advisory lock for the current process on the shared +memory segment \fIcore\fR for either shared/read-only (\fImode\fR is \f(CWMM_LOCK_RD\fR) +or exclusive/read-write (\fImode\fR is \f(CWMM_LOCK_RW\fR) operations between +\fIfork\fR\|(2)'ed child processes. +.Ip "int \fBmm_core_unlock\fR(const void *\fIcore\fR);" 4 +This function releases a previously acquired advisory lock for the current +process on the shared memory segment \fIcore\fR. +.Ip "size_t \fBmm_core_size\fR(const void *\fIcore\fR);" 4 +This returns the size in bytes of \fIcore\fR. This size is exactly the size which +was used for creating the shared memory area via \fImm_core_create\fR\|(3). The +function is provided just for convenience reasons to not require the +application to remember the memory size behind \fIcore\fR itself. +.Ip "size_t \fBmm_core_maxsegsize\fR(void);" 4 +This returns the number of bytes of a maximum-size shared memory segment which +is allowed to allocate via the \s-1MM\s0 library. It is between a few \s-1KB\s0 and the soft +limit of 64MB. +.Ip "size_t \fBmm_core_align2page\fR(size_t \fIsize\fR);" 4 +This is just a utility function which can be used to align the number \fIsize\fR +to the next virtual memory \fIpage\fR boundary used by the underlaying platform. +The memory page boundary under Unix platforms is usually somewhere between +2048 and 16384 bytes. You don't have to align the \fIsize\fR arguments of other +\fB\s-1MM\s0\fR library functions yourself, because this is already done internally. +This function is exported by the \fB\s-1MM\s0\fR library just for convenience reasons in +case an application wants to perform simular calculations for other purposes. +.Ip "size_t \fBmm_core_align2word\fR(size_t \fIsize\fR);" 4 +This is another utility function which can be used to align the number \fIsize\fR +to the next virtual memory \fIword\fR boundary used by the underlaying platform. +The memory word boundary under Unix platforms is usually somewhere between 4 +and 16 bytes. You don't have to align the \fIsize\fR arguments of other \fB\s-1MM\s0\fR +library functions yourself, because this is already done internally. This +function is exported by the \fB\s-1MM\s0\fR library just for convenience reasons in case +an application wants to perform simular calculations for other purposes. +.Sh "Low-Level Shared Memory \s-1API\s0" +.Ip "void \fBmm_lib_error_set\fR(unsigned int, const char *str);" 4 +This is a function which is used internally by the various \s-1MM\s0 function to set +an error string. It's usually not called directly from applications. +.Ip "char *\fBmm_lib_error_get\fR(void);" 4 +This is a function which is used internally by \fIMM_error\fR\|(3) and \fImm_error\fR\|(3) +functions to get the current error string. It's usually not called directly +from applications. +.Ip "int \fBmm_lib_version\fR(void);" 4 +This function returns a hex-value ``0x\fIV\fR\fI\s-1RR\s0\fR\fIT\fR\fI\s-1LL\s0\fR'\*(R' which describes the +current \s-1MM\s0 library version. \fIV\fR is the version, \fI\s-1RR\s0\fR the revisions, \fI\s-1LL\s0\fR +the level and \fIT\fR the type of the level (alphalevel=0, betalevel=1, +patchlevel=2, etc). For instance \s-1MM\s0 version 1.0.4 is encoded as 0x100204. The +reason for this unusual mapping is that this way the version number is +steadily \fIincreasing\fR. +.SH "RESTRICTIONS" +The maximum size of a continuous shared memory segment one can allocate +depends on the underlaying platform. This cannot be changed, of course. But +currently the high-level \fImalloc\fR\|(3)\-style API just uses a single shared memory +segment as the underlaying data structure for an \f(CWMM\fR object which means that +the maximum amount of memory a \f(CWMM\fR object represents also depends on the +platform. +.PP +This should be changed in later versions by allowing the high-level +\fImalloc\fR\|(3)\-style API to internally use multiple shared memory segments to form +the \f(CWMM\fR object. This way \f(CWMM\fR objects could have arbitrary sizes, although +the maximum size of an allocatable chunk still is bounded by the maximum size +of a shared memory segment. +.SH "SEE ALSO" +mm-\fIconfig\fR\|(1). +.PP +\fImalloc\fR\|(3), \fIcalloc\fR\|(3), \fIrealloc\fR\|(3), \fIstrdup\fR\|(3), \fIfree\fR\|(3), \fImmap\fR\|(2), \fIshmget\fR\|(2), +\fIshmctl\fR\|(2), \fIflock\fR\|(2), \fIfcntl\fR\|(2), \fIsemget\fR\|(2), \fIsemctl\fR\|(2), \fIsemop\fR\|(2). +.SH "HOME" +http://www.engelschall.com/sw/mm/ + +.SH "HISTORY" +This library was originally written in January 1999 by \fIRalf S.

On the first (lower) layer it hides all platform +dependent implementation details (allocation and locking) when dealing with +shared memory segments and on the second (higher) layer it provides a +high-level malloc(3)-style API for a convenient and well known way to work +with data-structures inside those shared memory segments. + +The abbreviation B<MM> is historically and originally comes from the phrase +``I<memory mapped>'' as used by the POSIX.1 mmap(2) function. Because this +facility is internally used by this library on most platforms to create the +shared memory segments. + +=head2 LIBRARY STRUCTURE + +This library is structured into three main APIs which are internally based on +each other: + +=over 4 + +=item B<Global Malloc-Replacement API> + +This is the most high-level API which directly can be used as replacement API +for the POSIX.1 memory allocation API (malloc(2) and friends). This is +useful when converting I<heap> based data structures to I<shared memory> +based data structures without the need to change the code dramatically. All +which is needed is to prefix the POSIX.1 memory allocation functions with +C<MM_>, i.e. C<malloc> becomes C<MM_malloc>, C<strdup> becomes C<MM_strdup>, +etc. This API internally uses just a global C<MM*> pool for calling the +corresponding functions (with prefix C<mm_>) of the I<Standard Malloc-Style +API>. + +=item B<Standard Malloc-Style API> + +This is the standard high-level memory allocation API. It's interface is +similar to the I<Global Malloc-Replacement API> but it uses an explicit C<MM*> +pool to operate on. That's why every function of this API has an argument of +type C<MM*> as the first argument. This API provides a comfortable way to +work with small dynamically allocated shared memory chunks inside large +statically allocated shared memory segments. It's internally based on the +I<Low-Level Shared Memory API> for creating the underlaying shared memory +segment. + +=item B<Low-Level Shared Memory API> + +This is the basis of the whole B<MM> library. It provides low-level functions +for creating shared memory segments with mutual exclusion (in short: I<mutex>) +capabilities in a portable way. Internally the shared memory and mutex +facility is implemented in various platform-dependent ways. A list of +implementation variants follows under the next topic. + +=back + +=head2 SHARED MEMORY IMPLEMENTATION + +Internally the shared memory facility is implemented in various +platform-dependent variants. Each has it's own advantages and disadvantages +(in addition to the fact that some variants aren't available at all on some +platforms). The MM libraries configuration procedure tried hard to make a good +decision. The implemented variants are now given for overview and background +reasons with their advantages and disadvantages and in an ascending order, +i.e. the MM configuration mechanism chooses the last available one in the list +as the preferred variant. + +=over 4 + +=item Classical mmap(2) on temporary file (MMFILE) + +I<Advantage:> maximum portable. +I<Disadvantage:> needs a temporary file on the filesystem + +=item mmap(2) via POSIX.1 shm_open(3) on temporary file (MMPOSX) + +I<Advantage:> standardized by POSIX.1 and theoretically portable. +I<Disadvantage:> needs a temporary file on the filesystem and is +is usually not available on existing Unix platform. + +=item SVR4-style mmap(2) on C</dev/zero> device (MMZERO) + +I<Advantage:> widely available on mostly portable on SVR4 platforms. +I<Disadvantage:> needs the C</dev/zero/> device and an mmap(2) +which supports memory mapping through it. + +=item 4.4BSD-style mmap(2) via C<MAP_ANON> facility (MMANON) + +I<Advantage:> doesn't need a temporary file or external device +I<Disadvantage:> usually only available on BSD platforms and derivatives. + +=item SysV IPC shmget(2) (IPCSHM) + +I<Advantage:> doesn't need a temporary file or external device +I<Disadvantage:> although available on mostly all modern Unix platforms it has +hard restrictions like the maximum size of a single shared memory segment (can +be as small as 100KB, but depends on the platform). + +=back + +=head2 LOCKING IMPLEMENTATION + +As for the shared memory facility, internally the locking facility is +implemented in various platform-dependent variants. A short overview of +implemented variants is given: + +=over 4 + +=item 4.2BSD-style flock(2) on temporary file (FLOCK) + +I<Advantage:> exists on a lot of platforms, especially on older Unix +derivates. I<Disadvantage:> needs a temporary file on the filesystem and has +to reopen filedescriptors to it in each(!) fork(2)ed child process. + +=item SysV IPC semget(2) (IPCSEM) + +I<Advantage:> exists on a lot of platforms and doesn't need a temporary file. +I<Disadvantage:> an unmeant termination of the application leads to a +semaphore leak because the facility doesn't allow an "remove in advance" trick +(as the IPC shared memory facility does!) for safe cleanups. + +=item SVR4-style fcntl(2) on temporary file (FCNTL) + +I<Advantage:> exists on a lot of platforms and is also the most powerful +variant (although not always the fastest one). I<Disadvantage:> needs a +temporary file. + +=back + +=head2 MEMORY ALLOCATION STRATEGY + +The memory allocation strategy the I<Standard Malloc-Style API> functions use +internally is the following: + +=over 4 + +=item B<Allocation> + +When a chunk of memory has to be allocated, the internal list of free chunks +is searched for a minimal-sized chunk which is larger or equal than the size +of the to be allocated chunk (some sort of a I<best fit algorithm>). + +When a chunk is found which matches this best-fit criteria, but is still a lot +larger than the requested size, it is split into two chunks: One with exactly +the requested size (which is the resulting chunk) and one with the remaining +size (which is immediately re-inserted into the list of free chunks). + +When no fitting chunk is found at all in the list of free chunks, a new one is +created from the spare area of the shared memory segment until the segment is +full (in which case an I<out of memory> error occurs). + +=item B<Deallocation> + +When a chunk of memory has to be deallocated, it is inserted in sorted manner +into the internal list of free chunks. The insertion operation automatically +merges the chunk with a previous and/or next free chunk when possible, i.e. +the free chunks stay physically seamless (one after another) in memory, to +automatically form larger free chunks out of smaller ones. + +This way the shared memory segment is automatically defragmented when memory +is deallocated. + +=back + +This strategy reduces memory waste and fragmentation caused by small and +frequent allocations and deallocations to a minimum. + +The internal implementation of the list of free chunks is not specially +optimized (for instance by using binary search trees or even splay trees, +etc.), because it's assumed that the total amount of entries in the list of +free chunks is always small (caused both by the fact that shared memory +segments are usually a lot smaller than heaps and the fact that we always +defragment by merging the free chunks when possible). + +=head1 API FUNCTIONS + +In the following all API functions are described in detail. +The order directly follows the one in the SYNOPSIS. + +=head2 Global Malloc-Replacement API + +=over 4 + +=item int B<MM_create>(size_t I<size>, const char *I<file>); + +This initialized the global shared memory pool with I<size> and I<file> and +has be called I<before> any fork(2) operations are performed by the +application. + +=item int B<MM_permission>(mode_t I<mode>, uid_t I<owner>, gid_t I<group>); + +This sets the filesystem I<mode>, I<owner> and I<group> for the global shared +memory pool (has effects only when the underlaying shared memory segment +implementation is actually based on external auxiliary files). The arguments +are directly passed through to chmod(2) and chown(2). + +=item void B<MM_destroy>(void); + +This destroys the global shared memory pool and should be called I<after> all +child processes were killed. + +=item int B<MM_lock>(mm_lock_mode I<mode>); + +This locks the global shared memory pool for the current process in order to +perform either shared/read-only (I<mode> is C<MM_LOCK_RD>) or +exclusive/read-write (I<mode> is C<MM_LOCK_RW>) operations inside the global +shared memory pool. + +=item int B<MM_unlock>(void); + +This unlocks the global shared memory pool for the current process after +mutual exclusion operations were performed inside the global shared memory +pool. + +=item void *B<MM_malloc>(size_t I<size>); + +Identical to the POSIX.1 malloc(3) function but instead of allocating +memory from the I<heap> it allocates it from the global shared memory pool. + +=item void B<MM_free>(void *I<ptr>); + +Identical to the POSIX.1 free(3) function but instead of deallocating +memory in the I<heap> it deallocates it in the global shared memory pool. + +=item void *B<MM_realloc>(void *I<ptr>, size_t I<size>); + +Identical to the POSIX.1 realloc(3) function but instead of reallocating +memory in the I<heap> it reallocates it inside the global shared memory pool. + +=item void *B<MM_calloc>(size_t I<number>, size_t I<size>); + +Identical to the POSIX.1 calloc(3) function but instead of allocating and +initializing memory from the I<heap> it allocates and initializes it from the +global shared memory pool. + +=item char *B<MM_strdup>(const char *I<str>); + +Identical to the POSIX.1 strdup(3) function but instead of creating the +string copy in the I<heap> it creates it in the global shared memory pool. + +=item size_t B<MM_sizeof>(const void *I<ptr>); + +This function returns the size in bytes of the chunk starting at I<ptr> when +I<ptr> was previously allocated with MM_malloc(3). The result is undefined +when I<ptr> was not previously allocated with MM_malloc(3). + +=item size_t B<MM_maxsize>(void); + +This function returns the maximum size which is allowed +as the first argument to the MM_create(3) function. + +=item size_t B<MM_available>(void); + +Returns the amount in bytes of still available (free) memory in the global +shared memory pool. + +=item char *B<MM_error>(void); + +Returns the last error message which occurred inside the B<MM> library. + +=back + +=head2 Standard Malloc-Style API + +=over 4 + +=item MM *B<mm_create>(size_t I<size>, const char *I<file>); + +This creates a shared memory pool which has space for approximately a total of +I<size> bytes with the help of I<file>. Here I<file> is a filesystem path to a +file which need not to exist (and perhaps is never created because this +depends on the platform and chosen shared memory and mutex implementation). +The return value is a pointer to an C<MM> structure which should be treated as +opaque by the application. It describes the internals of the created shared +memory pool. In case of an error C<NULL> is returned. A I<size> of 0 means to +allocate the maximum allowed size which is platform dependent and between a +few KB and the soft limit of 64MB. + +=item int B<mm_permission>(MM *I<mm>, mode_t I<mode>, uid_t I<owner>, gid_t I<group>); + +This sets the filesystem I<mode>, I<owner> and I<group> for the shared memory +pool I<mm> (has effects only when the underlaying shared memory segment +implementation is actually based on external auxiliary files). The arguments +are directly passed through to chmod(2) and chown(2). + +=item void B<mm_destroy>(MM *I<mm>); + +This destroys the complete shared memory pool I<mm> and with it all chunks +which were allocated in this pool. Additionally any created files on the +filesystem corresponding the to shared memory pool are unlinked. + +=item int B<mm_lock>(MM *I<mm>, mm_lock_mode I<mode>); + +This locks the shared memory pool I<mm> for the current process in order to +perform either shared/read-only (I<mode> is C<MM_LOCK_RD>) or +exclusive/read-write (I<mode> is C<MM_LOCK_RW>) operations inside the global +shared memory pool. + +=item int B<MM_unlock>(MM *I<mm>); + +This unlocks the shared memory pool I<mm> for the current process after mutual +exclusion operations were performed inside the global shared memory pool. + +=item void *B<mm_malloc>(MM *I<mm>, size_t I<size>); + +This function allocates I<size> bytes from the shared memory pool I<mm> and +returns either a (virtual memory word aligned) pointer to it or C<NULL> in +case of an error (out of memory). It behaves like the POSIX.1 malloc(3) +function but instead of allocating memory from the I<heap> it allocates it +from the shared memory segment underlaying I<mm>. + +=item void B<mm_free>(MM *I<mm>, void *I<ptr>); + +This deallocates the chunk starting at I<ptr> in the shared memory pool I<mm>. +It behaves like the POSIX.1 free(3) function but instead of deallocating +memory from the I<heap> it deallocates it from the shared memory segment +underlaying I<mm>. + +=item void *B<mm_realloc>(MM *I<mm>, void *I<ptr>, size_t I<size>); + +This function reallocates the chunk starting at I<ptr> inside the shared +memory pool I<mm> with the new size of I<size> bytes. It behaves like the +POSIX.1 realloc(3) function but instead of reallocating memory in the +I<heap> it reallocates it in the shared memory segment underlaying I<mm>. + +=item void *B<mm_calloc>(MM *I<mm>, size_t I<number>, size_t I<size>); + +This is similar to mm_malloc(3), but additionally clears the chunk. It behaves +like the POSIX.1 calloc(3) function. It allocates space for I<number> +objects, each I<size> bytes in length from the shared memory pool I<mm>. The +result is identical to calling mm_malloc(3) with an argument of ``I<number> * +I<size>'', with the exception that the allocated memory is initialized to nul +bytes. + +=item char *B<mm_strdup>(MM *I<mm>, const char *I<str>); + +This function behaves like the POSIX.1 strdup(3) function. It allocates +sufficient memory inside the shared memory pool I<mm> for a copy of the string +I<str>, does the copy, and returns a pointer to it. The pointer may +subsequently be used as an argument to the function mm_free(3). If +insufficient shared memory is available, C<NULL> is returned. + +=item size_t B<mm_sizeof>(const void *I<ptr>); + +This function returns the size in bytes of the chunk starting at I<ptr> when +I<ptr> was previously allocated with mm_malloc(3). The result is undefined +when I<ptr> was not previously allocated with mm_malloc(3). + +=item size_t B<mm_maxsize>(void); + +This function returns the maximum size which is allowed as the first argument +to the mm_create(3) function. + +=item size_t B<mm_available>(MM *I<mm>); + +Returns the amount in bytes of still available (free) memory in the +shared memory pool I<mm>. + +=item char *B<mm_error>(void); + +Returns the last error message which occurred inside the B<MM> library. + +=item void B<mm_display_info>(MM *I<mm>); + +This is debugging function which displays a summary page for the shared memory +pool I<mm> describing various internal sizes and counters. + +=back + +=head2 Low-Level Shared Memory API + +=over 4 + +=item void *B<mm_core_create>(size_t I<size>, const char *I<file>); + +This creates a shared memory area which is at least I<size> bytes in size with +the help of I<file>. The value I<size> has to be greater than 0 and less or +equal the value returned by mm_core_maxsegsize(3). Here I<file> is a +filesystem path to a file which need not to exist (and perhaps is never +created because this depends on the platform and chosen shared memory and +mutex implementation). The return value is either a (virtual memory word +aligned) pointer to the shared memory segment or C<NULL> in case of an error. +The application is guaranteed to be able to access the shared memory segment +from byte 0 to byte I<size>-1 starting at the returned address. + +=item int B<mm_core_permission>(void *I<core>, mode_t I<mode>, uid_t I<owner>, gid_t I<group>); + +This sets the filesystem I<mode>, I<owner> and I<group> for the shared memory +segment I<code> (has effects only when the underlaying shared memory segment +implementation is actually based on external auxiliary files). The arguments +are directly passed through to chmod(2) and chown(2). + +=item void B<mm_core_delete>(void *I<core>); + +This deletes a shared memory segment I<core> (as previously returned by a +mm_core_create(3) call). After this operation, accessing the segment starting +at I<core> is no longer allowed and will usually lead to a segmentation fault. + +=item int B<mm_core_lock>(const void *I<core>, mm_lock_mode I<mode>); + +This function acquires an advisory lock for the current process on the shared +memory segment I<core> for either shared/read-only (I<mode> is C<MM_LOCK_RD>) +or exclusive/read-write (I<mode> is C<MM_LOCK_RW>) operations between +fork(2)'ed child processes. + +=item int B<mm_core_unlock>(const void *I<core>); + +This function releases a previously acquired advisory lock for the current +process on the shared memory segment I<core>. + +=item size_t B<mm_core_size>(const void *I<core>); + +This returns the size in bytes of I<core>. This size is exactly the size which +was used for creating the shared memory area via mm_core_create(3). The +function is provided just for convenience reasons to not require the +application to remember the memory size behind I<core> itself. + +=item size_t B<mm_core_maxsegsize>(void); + +This returns the number of bytes of a maximum-size shared memory segment which +is allowed to allocate via the MM library. It is between a few KB and the soft +limit of 64MB. + +=item size_t B<mm_core_align2page>(size_t I<size>); + +This is just a utility function which can be used to align the number I<size> +to the next virtual memory I<page> boundary used by the underlaying platform. +The memory page boundary under Unix platforms is usually somewhere between +2048 and 16384 bytes. You don't have to align the I<size> arguments of other +B<MM> library functions yourself, because this is already done internally. +This function is exported by the B<MM> library just for convenience reasons in +case an application wants to perform simular calculations for other purposes. + +=item size_t B<mm_core_align2word>(size_t I<size>); + +This is another utility function which can be used to align the number I<size> +to the next virtual memory I<word> boundary used by the underlaying platform. +The memory word boundary under Unix platforms is usually somewhere between 4 +and 16 bytes. You don't have to align the I<size> arguments of other B<MM> +library functions yourself, because this is already done internally. This +function is exported by the B<MM> library just for convenience reasons in case +an application wants to perform simular calculations for other purposes. + +=back + +=head2 Low-Level Shared Memory API + +=over 4 + +=item void B<mm_lib_error_set>(unsigned int, const char *str); + +This is a function which is used internally by the various MM function to set +an error string. It's usually not called directly from applications. + +=item char *B<mm_lib_error_get>(void); + +This is a function which is used internally by MM_error(3) and mm_error(3) +functions to get the current error string. It's usually not called directly +from applications. + +=item int B<mm_lib_version>(void); + +This function returns a hex-value ``0xI<V>I<RR>I<T>I<LL>'' which describes the +current MM library version. I<V> is the version, I<RR> the revisions, I<LL> +the level and I<T> the type of the level (alphalevel=0, betalevel=1, +patchlevel=2, etc). For instance MM version 1.0.4 is encoded as 0x100204. The +reason for this unusual mapping is that this way the version number is +steadily I<increasing>. + +=back + +=head1 RESTRICTIONS + +The maximum size of a continuous shared memory segment one can allocate +depends on the underlaying platform. This cannot be changed, of course. But +currently the high-level malloc(3)-style API just uses a single shared memory +segment as the underlaying data structure for an C<MM> object which means that +the maximum amount of memory a C<MM> object represents also depends on the +platform. + +This should be changed in later versions by allowing the high-level +malloc(3)-style API to internally use multiple shared memory segments to form +the C<MM> object. This way C<MM> objects could have arbitrary sizes, although +the maximum size of an allocatable chunk still is bounded by the maximum size +of a shared memory segment. + +=head1 SEE ALSO + +mm-config(1). + +malloc(3), calloc(3), realloc(3), strdup(3), free(3), mmap(2), shmget(2), +shmctl(2), flock(2), fcntl(2), semget(2), semctl(2), semop(2). + +=head1 HOME + +=for html +<a href="http://www.engelschall.com/sw/mm/">http://www.engelschall.com/sw/mm/</a> + +=for text +http://www.engelschall.com/sw/mm/ + +=for man +http://www.engelschall.com/sw/mm/ + +=head1 HISTORY + +This library was originally written in January 1999 by I<Ralf S.
