BCMP(3)                 NetBSD 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 identi- cal. The strings may overlap. This function is obsolete. The equivalent function memcmp(3) should be used instead.
SEE ALSO
memcmp(3), strcasecmp(3), strcmp(3), strcoll(3), strxfrm(3)
STANDARDS
The bcmp() function conforms to IEEE Std 1003.1-2001 (``POSIX.1''). The IEEE Std 1003.1-2004 (``POSIX.1'') revision marked it as legacy and rec- ommended the use of memcmp(3) instead. The IEEE Std 1003.1-2008 (``POSIX.1'') revision removed bcmp() from the specification.
HISTORY
A bcmp() function first appeared in 4.2BSD. NetBSD 9.99 May 5, 2012 NetBSD 9.99
