int bcmp(const void *s1, const void *s2, size_t n);General description
The bcmp() function compares the first n bytes of the area pointed to by s1 with the area pointed to by s2.
Note: The bcmp() function has been moved to the Legacy
Option group in Single UNIX Specification,
Version 3 and may be withdrawn in a future version. The memcmp()
function is preferred for portability.
Returned value
If s1 and s2 are identical, bcmp() returns 0. Otherwise, bcmp() returns nonzero. Both areas are assumed to be at least n bytes long.
If the value of n is zero, bcmp() returns 0.
There are no errno values defined.
