Hello https://man7.org/linux/man-pages/man3/malloc.3.html "The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc(), or realloc(). "
Agree that this is somewhat wrong.
Could this list refer to the other ways memory can be allocated too? free() accepts other memory. posix_memalign aligned_alloc memalign valloc pvalloc reallocarray That would be changing it to say :- "The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc(), realloc(), posix_memalign(), aligned_alloc(), memalign(), valloc(), reallocarray() or pvalloc()"
I don't like that list. It is incomplete (the first one that comes to my mind is asprintf(3)). Either we provide a _complete_ list of functions that can be free(3)d, which I think will be difficult to keep up to date, or we use the same wording as POSIX, and say that it deallocates memory allocated as if by malloc(3).
What are your thoughts? Thanks, Alex -- Alejandro Colomar Linux man-pages comaintainer; https://www.kernel.org/doc/man-pages/ http://www.alejandro-colomar.es/
