PROLOG

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

NAME

       wcschr -- wide-character string scanning operation

SYNOPSIS

       #include <wchar.h>

       wchar_t *wcschr(const wchar_t *ws, wchar_t wc);

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  wcschr() function shall locate the first occurrence of wc in the wide-character string pointed to by ws.  The application shall ensure
       that the value of wc is a character representable as a type wchar_t and a wide-character code corresponding to a  valid	character  in  the
       current locale. The terminating null wide-character code is considered to be part of the wide-character string.

RETURN VALUE

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

ERRORS

       No errors are defined.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       None.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.

NAME

       wmemchr -- find a wide character in memory

SYNOPSIS

       #include <wchar.h>

       wchar_t *wmemchr(const wchar_t *ws, wchar_t wc, size_t n);

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 wmemchr() function shall locate the first occurrence of wc in the initial n wide characters of the object pointed to by ws.	This func-
       tion shall not be affected by locale and all wchar_t values shall be treated identically. The null wide character and  wchar_t  values  not
       corresponding to valid characters shall not be treated specially.

       If n is zero, the application shall ensure that ws is a valid pointer and the function behaves as if no valid occurrence of wc is found.

RETURN VALUE

       The  wmemchr() function shall return a pointer to the located wide character, or a null pointer if the wide character does not occur in the
       object.

ERRORS

       No errors are defined.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       None.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
