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.


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.
