bcmp9
Returns 0 if and only if the buffers have identical contents.
Usage
int bcmp(const void * a, const void * b, size_t len);
Arguments
a
pointer to first buffer.
b
pointer to second buffer.
len
size of buffers.
Overview
The sign or magnitude of a non-zero return value has no particular meaning, and architectures may implement their own more efficient bcmp. So while this particular implementation is a simple (tail) call to memcmp, do not rely on anything but whether the return value is zero or non-zero.
