I don't think that's a true. If it were general knowledge then we wouldn't see the pattern of `if (ptr) free(ptr)` in the code to begin with. And overall, I don't believe most "resource-release" functions have this behavior. For example fclose, closedir, munmap etc don't accept NULL arg. So `free` is more of an exception to the general knowledge. - NRK
