====== strncmp ======

<code c>
#include <stdlib.h>

int strncmp(const char *str1, const char *str2, size_t n);
</code>

The strcmp() function compares the two strings ''s1'' and ''s2''.  It returns an integer less than, equal to, or greater than zero if ''s1'' is found, respectively, to be less than, to match, or be greater than ''s2''. The strncmp() function is similar, except it only compares the first (at most) n characters of ''s1'' and ''s2''.
