bcmp(3)                  BSD 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.

HISTORY

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