[Asterisk-Dev] calloc vs malloc ?

[Luigi Rizzo]

any reason why the sequences

	foo = malloc(sizeof(*foo));
	if (!foo) { /* error handling */ }
	memset(foo, 0, sizeof(*foo));

are not implemented with proper calloc calls ?

	foo = calloc(1, sizeof(*foo));
	if (!foo) { /* error handling */ }

Apart from making the code more robust (because a malloc
without a comment epxlaining why clearing is not necessary
would immediately trigger the developer's attention),
by using calloc() we would also give
the allocator a chance to hand us clean pages without
redoing the clearing ourselves.
