bcmp – compare byte string

LIBRARY SYNOPSIS DESCRIPTION SEE ALSO HISTORY

Standard C Library (libc, -lc)

#include <strings.h>

int
bcmp(const void *b1, const void *b2, size_t len);

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.

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