wcsrchr - Locate Wide Character in String

Syntax

#include <wchar.h>
wchar_t *wcsrchr(const wchar_t *string, wint_t character);

wcsrchr locates the last occurrence of character in the string pointed to by string. The terminating wchar_t null character is considered to be part of the string.

wcsrchr returns a pointer to the character, or a NULL pointer if character does not occur in the string.

This example compares the use of wcschr and wcsrchr. It searches the string for the first and last occurrence of p in the wide character string.

#include <stdio.h>
#include <wchar.h>

#define  SIZE          40

int main(void)
{
   wchar_t buf[SIZE] = L"computer program";
   wchar_t *ptr;
   int ch = 'p';

   /* This illustrates wcschr                                                 */

   ptr = wcschr(buf, ch);
   printf("The first occurrence of %c in '%ls' is '%ls'\n", ch, buf, ptr);

   /* This illustrates wscrchr                                                */

   ptr = wcsrchr(buf, ch);
   printf("The last occurrence of %c in '%ls' is '%ls'\n", ch, buf, ptr);
   return 0;

   /****************************************************************************
      The output should be:

      The first occurrence of p in 'computer program' is 'puter program'
      The last occurrence of p in 'computer program' is 'program'
