NAME

13       wcsstr — find a wide-character substring
14

SYNOPSIS

16       #include <wchar.h>
17
18       wchar_t *wcsstr(const wchar_t *restrict ws1,
19           const wchar_t *restrict ws2);
20

DESCRIPTION

22       The functionality described on this reference page is aligned with  the
23       ISO C  standard.  Any  conflict between the requirements described here
24       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2008
25       defers to the ISO C standard.
26
27       The  wcsstr()  function  shall locate the first occurrence in the wide-
28       character string pointed to by ws1 of the sequence of  wide  characters
29       (excluding  the  terminating null wide character) in the wide-character
30       string pointed to by ws2.
31

RETURN VALUE

33       Upon successful completion, wcsstr() shall  return  a  pointer  to  the
34       located  wide-character string, or a null pointer if the wide-character
35       string is not found.
36
37       If ws2 points to a wide-character string with zero length, the function
38       shall return ws1.
