       This  manual  page  is part of the POSIX Programmer's Manual.  The Linux implementation of
       this interface may differ (consult the corresponding Linux  manual  page  for  details  of
       Linux behavior), or the interface may not be implemented on Linux.

NAME

       wcsstr — find a wide-character substring

SYNOPSIS

       #include <wchar.h>

       wchar_t *wcsstr(const wchar_t *restrict ws1,
           const wchar_t *restrict ws2);

DESCRIPTION

       The functionality described on this reference page is aligned with the ISO C standard. Any
       conflict between the requirements described here and the ISO C standard is  unintentional.
       This volume of POSIX.1‐2008 defers to the ISO C standard.

       The  wcsstr()  function  shall  locate  the  first occurrence in the wide-character string
       pointed to by ws1 of the sequence of wide characters (excluding the terminating null  wide
       character) in the wide-character string pointed to by ws2.

RETURN VALUE

       Upon  successful completion, wcsstr() shall return a pointer to the located wide-character
       string, or a null pointer if the wide-character string is not found.

       If ws2 points to a wide-character string with zero length, the function shall return ws1.
