<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++.

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

int main ()
{
  wchar_t wcs[] = L"This is a sample wide string";
  wchar_t * pwc;
  wprintf (L"Looking for the 's' character in \"%ls\"...\n",wcs);
  pwc=wcschr(wcs,L's');
  while (pwc!=NULL)
  {
    wprintf (L"found at %d\n",pwc-wcs+1);
    pwc=wcschr(pwc+1,L's');
  }
  return 0;
}
