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,
     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.

     This function is obsolete.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
     recommended 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.
