The memory must be freed with DEALLOCATE_LOCAL before the + * function that made the allocation returns. You should not ask for + * large blocks of memory with this function, since on many platforms + * the memory comes from the stack, which may have limited size. + * + * void DEALLOCATE_LOCAL(void *) + * Frees the memory allocated by ALLOCATE_LOCAL. Omission of this + * step may be harmless on some platforms, but will result in + * memory leaks or worse on others. + * + * Before including this file, you should define two macros, + * ALLOCATE_LOCAL_FALLBACK and DEALLOCATE_LOCAL_FALLBACK, that have the + * same characteristics as ALLOCATE_LOCAL and DEALLOCATE_LOCAL. The + * header uses the fallbacks if it doesn't know a "better" way to define + * ALLOCATE_LOCAL and DEALLOCATE_LOCAL.
