BCMP(3)                  BSD Library Functions Manual                  BCMP(3)

NAME
     bcmp -- compare byte string

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     ##include <>

     int
     bcmp(const void *b1, const void *b2, sizet 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.
