In the case:
if ((x = malloc(len)) == 0) {
--- error code
if (!(x = malloc(len))) {
--- error code
The C standard treats 0 as a special case. Many times one might find many
cases where NULL is defined as plain 0, not (void *)0 or 0L. It is more
correct to test a pointer to equality or inequality rather than to negate
it.
