MEMCMP(3) BSD Library Functions Manual MEMCMP(3) NAME memcmp -- compare byte string LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <string.h> int memcmp(const void *s1, const void *s2, size_t n); DESCRIPTION The memcmp() function compares byte string s1 against byte string s2. Both strings are assumed to be n bytes long. RETURN VALUES The memcmp() function returns zero if the two strings are identical, oth-erwise otherwise erwise returns the difference between the first two differing bytes (treated as unsigned char values, so that `\200' is greater than `\0', for example). Zero-length strings are always identical. SEE ALSO bcmp(3), strcasecmp(3), strcmp(3), strcoll(3), strxfrm(3) STANDARDS The memcmp() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
