14 The wcscasecmp() function is the wide-character equivalent of the str‐
15 casecmp() function. It compares the wide-character string pointed to by
16 s1 and the wide-character string pointed to by s2, ignoring case dif‐
17 ferences (towupper(), towlower()).
18
20 The wcscasecmp() function returns zero if the wide-character strings at
21 s1 and s2 are equal except for case distinctions. It returns a positive
22 integer if s1 is greater than s2, ignoring case. It returns a negative
23 integer if s1 is smaller than s2, ignoring case.

26 This function is a GNU extension.

32 The behaviour of wcscasecmp() depends on the LC_CTYPE category of the
33 current locale.
