not really. POSIX says malloc(0) is implementation defined (so it may return a unique address, or it may return NULL). no userspace code assuming malloc(0) will return non-NULL is correct. -mike
Argh! Valid point - So we can basically say that it does not matter what we do (return NULL or return a valid pointer). Because the behaviour is implementation specific, it is up to the caller to deal with it.
