16 The strcasecmp() function compares the two strings s1 and s2, ignoring
17 the case of the characters. It returns an integer less than, equal to,
18 or greater than zero if s1 is found, respectively, to be less than, to
19 match, or be greater than s2.
20
21 The strncasecmp() function is similar, except it compares the only
22 first n bytes of s1.
23
25 The strcasecmp() and strncasecmp() functions return an integer less
26 than, equal to, or greater than zero if s1 (or the first n bytes
27 thereof) is found, respectively, to be less than, to match, or be
28 greater than s2.
