BCMP(3) BSD Library Functions Manual BCMP(3)NAMEbcmp — 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.
SEE ALSOmemcmp(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 recom‐
mended 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.
