As far as I understand, it depends on the implementation of the memory allocator. I did not find any working examples, but I think that allocator using mmap() system call to get memory from OS and caring to call munmap() when the chunk is no longer nesessary would return the memory back. Thus any modern Unix would be able to do that. Solaris has mapmalloc library. Its manual page hints that allocator from standard C library uses sbrk() to get memory, so returning it back is impossible in this case. --Tima _______________________________________________ Discuss-gnustep mailing list Discuss-gnustep@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnustep
