wcscasecmp, wcsncasecmp —
#include <wchar.h>
int
  
  wcscasecmp(const
    wchar_t *s1, const
    wchar_t *s2);
int
  
  wcsncasecmp(const
    wchar_t *s1, const
    wchar_t *s2, size_t
    len);
wcscasecmp() and
  wcsncasecmp() functions compare the nul-terminated
  strings s1 and s2 and return an
  integer greater than, equal to, or less than 0, according to whether
  s1 is lexicographically greater than, equal to, or less
  than s2 after translation of each corresponding
  character to lower-case. The strings themselves are not modified.
The wcsncasecmp() function compares at
    most len characters.
wcscasecmp() and
  wcsncasecmp() functions conform to
  IEEE Std 1003.1-2008 (“POSIX.1”).
wcscasecmp() and
  wcsncasecmp() functions first appeared in
  NetBSD 4.0.
wcsncasecmp() always
  returns 0.
