Compares a specified number of characters from two wide-character strings, ignoring case.
#include <wchar.h> int wcsncasecmp ( const wchar_t *ws1, const wchar_t *ws2, size_t n);
(IN) Points to the first wide-character string to compare.
(IN) Points to the second wide-character string to compare.
(IN) Specifies the number of characters to compare.
Returns 0 if the two strings match, for the specified number of characters. Otherwise, it returns a positive integer if ws1 is greater than ws2 and a negative integer if ws1 is less than ws2.
The wcsncasecmp function is identical to wcsncmp, except that the characters of each string are converted to lowercase before comparison.
