BCMP(3) BSD Library Functions Manual BCMP(3)
NAME
bcmp -- 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.
