Name

wcswcs - find a wide substring

Library

libc.lib

Synopsis

#include <wchar.h>

wchar_t * wcswcs (const wchar_t *wcs1, const wchar_t *wcs2);

Detailed description

The wcswcs() function locates the first occurrence of the wide-character string pointed by wcs1 (excluding the terminating ’\0’ character in the wide-character string pointed by wcs2.

Examples

#include <wchar.h>
/* Illustrates how to use wcswcs API */
int example_wcswcs()
{  
  /* source wide character string */
 wchar_t *buf[20] = { L"fkhsdf%%38",L"rtti123123", };
 wchar_t *str  = wcswcs(buf[0],L"");
 wchar_t *str1 = wcswcs(buf[1],L"\0");
 if(wcscmp(str,buf[0]))
   return 1;
 if(wcscmp(str1,buf[1]))
   return 1
 return 0;
}

Return value

The wcswcs() on success returns a pointer to the located wide-character string and returns a NULL pointer if the wide-charcter string was not found.

If wcs2 is a wide-character string with length as zero, the function returns wcs1.
