BCMP(3)			    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, re-
       turning	zero  if they are identical, non-zero otherwise.  Both strings
       are assumed to be len bytes long.  Zero-length strings are always iden-
       tical.

       The strings may overlap.

SEE ALSO

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