wcschr - wide-character string scanning operation
wchar_t *wcschr(const wchar_t *ws, wchar_t wc);
[CX] The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of IEEE Std 1003.1-2001 defers to the ISO C standard.
The wcschr() function shall locate the first occurrence of wc in the wide-character string pointed to by ws. The application shall ensure that the value of wc is a character representable as a type wchar_t and a wide-character code corresponding to a valid character in the current locale. The terminating null wide-character code is considered to be part of the wide-character string.
Upon completion, wcschr() shall return a pointer to the wide-character code, or a null pointer if the wide-character code is not found.
No errors are defined.
