5.45 wcscasecmp—case-insensitive wide character string compare

Synopsis

     #include <wchar.h>
     int wcscasecmp(const wchar_t *a, const wchar_t *b);
     

Description
wcscasecmp compares the wide character string at a to the wide character string at b in a case-insensitive manner.

If *a sorts lexicographically after *b (after both are converted to uppercase), wcscasecmp returns a number greater than zero. If the two strings match, wcscasecmp returns zero. If *a sorts lexicographically before *b, wcscasecmp returns a number less than zero.

wcscasecmp requires no supporting OS subroutines. It uses tolower() from elsewhere in this library.
