Stated another way, all necessary global variables and functions are members of a big C++ object. This object's class is CPerlObj. This allows a Perl Host to have multiple, independent perl interpreters in the same process space. This is very important on Win32 systems as the overhead of process creation is quite high -- this could be even higher than the script compile and execute time for small scripts. The perl executable implementation on Win32 is composed of perl.exe (the Perl Host) and perlX.dll. (the Perl Core). This allows the same Perl Core to easily be embedded in other applications that use the perl interpreter. +-----------+ | Perl Host | +-----------+ ^ | v +-----------+ +-----------+ | Perl Core |<->| Extension | +-----------+ +-----------+ ... Defining PERL_OBJECT has the following effects: PERL CORE 1. CPerlObj is defined (this is the PERL_OBJECT) 2. all static functions that needed to access either global variables or functions needed are made member functions 3. all writable static variables are made member variables 4. all global variables and functions are defined as: #define var CPerlObj::PL_var #define func CPerlObj::Perl_func * these are in embed.h This necessitated renaming some local variables and functions that had the same name as a global variable or function. This was probably a _good_ thing anyway. EXTENSIONS 1. Access to global variables and perl functions is through a pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is made transparent to extension developers by the following macros: #define var pPerl->PL_var #define func pPerl->Perl_func * these are done in objXSUB.h This requires that the extension be compiled as C++, which means that the code must be ANSI C and not K&R C. For K&R extensions, please see the C API notes located in Win32/GenCAPI.pl. This script creates a perlCAPI.lib that provides a K & R compatible C interface to the PERL_OBJECT. 2. Local variables and functions cannot have the same name as perl's variables or functions since the macros will redefine these. Look for this if you get some strange error message and it does not look like the code that you had written. This often happens with variables that are local to a function. PERL HOST 1. The perl host is linked with perlX.lib to get perl_alloc. This function will return a pointer to CPerlObj (the PERL_OBJECT). It takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h for more information on this). 2. The perl host calls the same functions as normally would be called in setting up and running a perl script, except that the functions are now member functions of the PERL_OBJECT. */ class CPerlObj; #define STATIC #define CPERLscope(x) CPerlObj::x #define CALL_FPTR(fptr) (this->*fptr) #define pTHXo CPerlObj *pPerl #define pTHXo_ pTHXo, #define _pTHXo ,pTHXo #define aTHXo this #define aTHXo_ this, #define _aTHXo ,this #define PERL_OBJECT_THIS aTHXo #define PERL_OBJECT_THIS_ aTHXo_ #define _PERL_OBJECT_THIS _aTHXo #define dTHXoa(a) pTHXo = (CPerlObj *)a #define dTHXo dTHXoa(PERL_GET_INTERP) #define pTHXx void #define pTHXx_ #define _pTHXx #define aTHXx #define aTHXx_ #define _aTHXx #else /* !PERL_OBJECT */ #ifdef PERL_IMPLICIT_CONTEXT # ifdef USE_THREADS struct perl_thread; # define pTHX register struct perl_thread *thr # define aTHX thr # define dTHXa(a) pTHX = (struct perl_thread *)a # define dTHX dTHXa(THR) # define dTHR dNOOP # else # ifndef MULTIPLICITY # define MULTIPLICITY # endif # define pTHX register PerlInterpreter *my_perl # define aTHX my_perl # define dTHXa(a) pTHX = (PerlInterpreter *)a # define dTHX dTHXa(PERL_GET_INTERP) # endif # define pTHX_ pTHX, # define _pTHX ,pTHX # define aTHX_ aTHX, # define _aTHX ,aTHX #endif #define STATIC static #define CPERLscope(x) x #define CPERLarg void #define CPERLarg_ #define _CPERLarg #define PERL_OBJECT_THIS #define _PERL_OBJECT_THIS #define PERL_OBJECT_THIS_ #define CALL_FPTR(fptr) (*fptr) #endif /* PERL_OBJECT */ #define CALLRUNOPS CALL_FPTR(PL_runops) #define CALLREGCOMP CALL_FPTR(PL_regcompp) #define CALLREGEXEC CALL_FPTR(PL_regexecp) #define CALLREG_INTUIT_START CALL_FPTR(PL_regint_start) #define CALLREG_INTUIT_STRING CALL_FPTR(PL_regint_string) #define CALLREGFREE CALL_FPTR(PL_regfree) #define CALLPROTECT CALL_FPTR(PL_protect) #define NOOP (void)0 #define dNOOP extern int Perl___notused #ifndef pTHX # define pTHX void # define pTHX_ # define _pTHX # define aTHX # define aTHX_ # define _aTHX # define dTHXa(a) dNOOP # define dTHX dNOOP #endif #ifndef pTHXo # define pTHXo pTHX # define pTHXo_ pTHX_ # define _pTHXo _pTHX # define aTHXo aTHX # define aTHXo_ aTHX_ # define _aTHXo _aTHX # define dTHXo dTHX #endif #ifndef pTHXx # define pTHXx register PerlInterpreter *my_perl # define pTHXx_ pTHXx, # define _pTHXx ,pTHXx # define aTHXx my_perl # define aTHXx_ aTHXx, # define _aTHXx ,aTHXx # define dTHXx dTHX #endif #undef START_EXTERN_C #undef END_EXTERN_C #undef EXTERN_C #ifdef __cplusplus # define START_EXTERN_C extern "C" { # define END_EXTERN_C } # define EXTERN_C extern "C" #else # define START_EXTERN_C # define END_EXTERN_C # define EXTERN_C extern #endif #ifdef OP_IN_REGISTER # ifdef __GNUC__ # define stringify_immed(s) #s # define stringify(s) stringify_immed(s) register struct op *Perl_op asm(stringify(OP_IN_REGISTER)); # endif #endif /* * STMT_START { statements; } STMT_END; * can be used as a single statement, as in * if (x) STMT_START { ... } STMT_END; else ... * * Trying to select a version that gives no warnings... */ #if !(defined(STMT_START) && defined(STMT_END)) # if defined(__GNUC__) && !defined(__STRICT_ANSI__) && !defined(__cplusplus) # define STMT_START (void)( /* gcc supports ``({ STATEMENTS; })'' */ # define STMT_END ) # else /* Now which other defined()s do we need here ??? */ # if (VOIDFLAGS) && (defined(sun) || defined(__sun__)) # define STMT_START if (1) # define STMT_END else (void)0 # else # define STMT_START do # define STMT_END while (0) # endif # endif #endif #define WITH_THX(s) STMT_START { dTHX; s; } STMT_END #define WITH_THR(s) STMT_START { dTHR; s; } STMT_END /* * SOFT_CAST can be used for args to prototyped functions to retain some * type checking; it only casts if the compiler does not know prototypes. */ #if defined(CAN_PROTOTYPE) && defined(DEBUGGING_COMPILE) #define SOFT_CAST(type) #else #define SOFT_CAST(type) (type) #endif #ifndef BYTEORDER /* Should never happen -- byteorder is in config.h */ # define BYTEORDER 0x1234 #endif /* Overall memory policy? */ #ifndef CONSERVATIVE # define LIBERAL 1 #endif #if 'A' == 65 && 'I' == 73 && 'J' == 74 && 'Z' == 90 #define ASCIIish #else #undef ASCIIish #endif /* * The following contortions are brought to you on behalf of all the * standards, semi-standards, de facto standards, not-so-de-facto standards * of the world, as well as all the other botches anyone ever thought of. * The basic theory is that if we work hard enough here, the rest of the * code can be a lot prettier.

Some things do work (such as quad pack/unpack on convex); also some systems use long long for the fpos_t typedef. That seems to work too.

Now we should get Quad_t in most systems: int64_t, long long, long, int, will do. Beware of LP32 systems (ILP32, ILP32LL64). Such systems have been used to sizeof(long) == sizeof(foo*). This is a bad assumption because then IV/UV have been 32 bits, too. Which, in turn means that even if the system has quads (e.g. long long), IV cannot be a quad. Introducing a 64-bit IV (because of long long existing) will introduce binary incompatibility. Summary: a long long system needs to add -DUSE_LONG_LONG to $ccflags to get quads -- and if its pointers are still 32 bits, this will break binary compatibility.
