NAME

wcsrchr - 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 IEEE Std 1003.1-2001 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.
