Web10 feb. 2024 · My malloc () in C using mmap () My latest school project was to implement malloc (), free (), realloc () and calloc () from the standard C library. I came up with something a bit similar to the glibc malloc (). It supports multi-threading; speed is pretty good according to my tests. Not very portable (meant for Linux 64bits and Darwin 64bits).

http://danluu.com/malloc-tutorial/ Web26 mei 2024 · Some limitations of this implementation include: There is no realloc (). This implementation uses unsigned int rather than size_t, so it does not follow the Standard, and can only allocate 32 bits on most 64-bit implementations. It passes a value of -1 as the file descriptor, which is not conformant to the POSIX standard.
