compare byte string
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include
<strings.h>
int
bcmp(const
void *b1, const void
*b2, size_t
len);
DESCRIPTION
The
bcmp()
function compares byte string b1 against byte string
b2, returning zero if they are identical, non-zero
otherwise. Both strings are assumed to be len bytes
long. Zero-length strings are always identical.
The strings may overlap.

HISTORY
A bcmp() function first appeared in
4.2BSD. Its prototype existed previously in
<string.h> before it was
moved to <strings.h> for
IEEE Std 1003.1-2001 (“POSIX.1”)
compliance.
