WCSSTR(3)                           Linux Programmer's Manual                           WCSSTR(3)



NAME
       wcsstr - locate a substring in a wide-character string

SYNOPSIS
       #include <wchar.h>

       wchar_t *wcsstr(const wchar_t *haystack, const wchar_t *needle);

DESCRIPTION
       The  wcsstr()  function  is  the  wide-character equivalent of the strstr(3) function.  It
       searches for the first occurrence of the wide-character string needle (without its  termi‐
       nating null wide character (L'\0')) as a substring in the wide-character string haystack.

RETURN VALUE
       The wcsstr() function returns a pointer to the first occurrence of needle in haystack.  It
       returns NULL if needle does not occur as a substring in haystack.

       Note the special case: If needle is the empty wide-character string, the return  value  is
       always haystack itself.

ATTRIBUTES
   Multithreading (see pthreads(7))
       The wcsstr() function is thread-safe.

CONFORMING TO
       C99.
