NAME
bcmp —
compare byte string
LIBRARY
library “libc”
SYNOPSIS
#include
<strings.h>
int
bcmp(const
void *b1, const void
*b2, size_t
len);
DESCRIPTION
Thebcmp()
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This function is obsolete.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
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.
