#include <wchar.h>
wchar_t *wcschr(const wchar_t *string1, wchar_t character);Searches string for the occurrence of character. The character may be a wide NULL character (\0). The wide NULL character at the end of string is included in the search. The wcschr() function operates on NULL-terminated wide-character strings. The argument to this function must contain a wide NULL character marking the end of the string.
The behavior of this wide-character function is affected by the LC_CTYPE category of the current locale. If you change the category, undefined results can occur.
If successful, wcschr() returns a pointer to the first occurrence of character in string.
If the character is not found, wcschr() returns a NULL pointer.
