WMEMCHR(3P) POSIX Programmer's Manual WMEMCHR(3P)PROLOG
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.
NAMEwmemchr - 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 wmemchr() function shall locate the first occurrence of wc in the
initial n wide characters of the object pointed to by ws. This function
shall not be affected by locale and all wchar_t values shall be treated
identically. The null wide character and wchar_t values not correspond‐
ing 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 char‐
acter, or a null pointer if the wide character does not occur in the
object.
ERRORS
