PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux

NAME

12       wcschr — wide-character string scanning operation
13

SYNOPSIS

15       #include <wchar.h>
16
17       wchar_t *wcschr(const wchar_t *ws, wchar_t wc);
18

DESCRIPTION

20       The functionality described on this reference page is aligned with  the
21       ISO C  standard.  Any  conflict between the requirements described here
22       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2017
23       defers to the ISO C standard.
24
25       The  wcschr()  function  shall locate the first occurrence of wc in the
26       wide-character string pointed to by ws.  The application  shall  ensure
27       that the value of wc is a character representable as a type wchar_t and
28       a wide-character code corresponding to a valid character in the current
29       locale.  The  terminating  null wide-character code is considered to be
30       part of the wide-character string.
31

RETURN VALUE

33       Upon completion, wcschr() shall return a pointer to the  wide-character
34       code, or a null pointer if the wide-character code is not found.
