int strncmp

int strncmp(const char *, const char *, size_t) __ATTR_PURE__

The strncmp() function is similar to strcmp(), except it only compares the first (at most) n characters of s1 and s2.


The strncmp() function returns an integer less than, equal to, or greater than zero if s1 (or the first n bytes thereof) is found, respectively, to be less than, to match, or be greater than s2.
