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 POSIX.1-2008 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.
First released in Issue 4. Derived from the MSE working draft.
The normative text is updated to avoid use of the term "must" for application requirements.
