Syntax

#include <wchar.h>
wchar_t *wcswcs(const wchar_t *string1, const wchar_t *string2);

wcswcs locates the first occurrence of string2 in the wide-character string pointed to by string1. In the matching process, wcswcs ignores the wchar_t null character that ends string2.

wcswcs returns a pointer to the located string or NULL if the string is not found. If string2 points to a string with zero length, wcswcs returns string1.

This example finds the first occurrence of the wide character string pr in buffer1.

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

#define  SIZE          40

int main(void)
{
   wchar_t buffer1[SIZE] = L"computer program";
   wchar_t *ptr;
   wchar_t *wch = L"pr";

   ptr = wcswcs(buffer1, wch);
   printf("The first occurrence of %ls in '%ls' is '%ls'\n", wch, buffer1, ptr);
   return 0;

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

      The first occurrence of pr in 'computer program' is 'program'
   ****************************************************************************/
