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     This function is obsolete.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.
