BCMP(3) BSD Library Functions Manual BCMP(3)NAME
bcmp -- compare byte string
Standard C Library (libc, -lc)
bcmp(const void *s1, const void *s2, size_t n);
The bcmp() function compares byte string s1 against byte string s2, returning zero if they are identical, non-zero otherwise. Both strings
are assumed to be n bytes long. Zero-length strings are always identical.
The strings may overlap.

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

bcmp - compare byte sequences
int bcmp(const void *s1, const void *s2, size_t n);
The bcmp() function compares the two byte sequences s1 and s2 of length n each. If they are equal, and in particular if n is zero, bcmp()
returns 0. Otherwise, it returns a nonzero result.
The bcmp() function returns 0 if the byte sequences are equal, otherwise a nonzero result is returned.

4.3BSD. This function is deprecated (marked as LEGACY in POSIX.1-2001): use memcmp(3) in new programs. POSIX.1-2008 removes the specifi-
cation of bcmp().
