This requires, + at the minimum, some sort of cooperative locking that ensures that + only one process at a time is changing any of the mmalloc managed + data structures (its ok for the mmalloc managed data regions to be + changed at any time since we don't care about their contents). + + * In order to support multiple processes using the mmalloc managed + region, the malloc descriptor needs to be broken into two parts, + one part which is specific to the given process and is maintained + separately on a per process basis, and another part which is common + to all processes. As an example, the file descriptor is specific + to a given process, as are the morecore and abortfunc pointers. + However magic[], the version number, the flags field, etc are + common to all processes. |
