BCMP(3) FreeBSD 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 identical. The strings may overlap. This function is obsolete. The equivalent function memcmp(3) should be used instead. SEE ALSO memcmp(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 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. FreeBSD 14.1-RELEASE-p8 May 5, 2012 FreeBSD 14.1-RELEASE-p8
