function
<cwchar>
wcschr
const wchar_t* wcschr (const wchar_t* ws, wchar_t wc); wchar_t* wcschr ( wchar_t* ws, wchar_t wc);
Locate first occurrence of character in wide string
Returns a pointer to the first occurrence of the wide character wc in the C wide string ws.
The terminating null wide character is considered part of the string. Therefore, it can also be located in order to retrieve a pointer to the end of a wide string.
This is the wide character equivalent of strchr (<cstring>).
Parameters
- ws
- C wide string.
- wc
- Wide character to be located.
Return Value
A pointer to the first occurrence of wc in ws.
If wc is not found, the function returns a null pointer.
Portability
In C, this function is only declared as:
wchar_t * wcschr ( const wchar_t *, wchar_t );
instead of the two overloaded versions provided in C++.
