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.
NAMEwcsrchr — wide-character string scanning operation
SYNOPSIS
#include <wchar.h>
wchar_t *wcsrchr(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 wcsrchr() function shall locate the last 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 shall be considered to
be part of the wide-character string.
RETURN VALUE
Upon successful completion, wcsrchr() shall return a pointer to the
wide-character code or a null pointer if wc does not occur in the wide-
character string.
