wcsrchr

const wchar_t* wcsrchr (const wchar_t* ws, wchar_t wc);
      wchar_t* wcsrchr (      wchar_t* ws, wchar_t wc);
Locate last occurrence of character in wide string
Returns a pointer to the last occurrence of wc in the C wide string ws.

The terminating null wide character is considered part of the string. Therefore, it can also be located 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 last 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 * wcsrchr ( const wchar_t *, wchar_t );

instead of the two overloaded versions provided in C++.

/* wcsrchr example */
#include <wchar.h>

int main ()
{
  wchar_t wcs[] = L"This is a sample wide string";
  wchar_t * pwc;
  pwc = wcsrchr (wcs,L's');
  wprintf (L"Last occurence of L's' found at %d \n",pwc-wcs+1);
  return 0;
}


Output:

Last occurrence of L's' found at 23
