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.

NAME

wcsrchr - wide-character string scanning operation

SYNOPSIS

#include <wchar.h>

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

DESCRIPTION

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.
