wmemchr(3C) Standard C Library Functions wmemchr(3C)NAMEwmemchr - find a wide-character in memory
SYNOPSIS
#include <wchar.h>
wchar_t *wmemchr(const wchar_t *ws, wchar_t wc, size_t n);
ISO C++
#include <wchar.h>
const wchar_t *wmemchr(const wchar_t *ws, wchar_t wc, size_t n);
#include <cwchar>
wchar_t *std::wmemchr(wchar_t *ws, wchar_t wc, size_t n);
DESCRIPTION
The wmemchr() function locates the first occurrence of wc in the ini‐
tial n wide-characters of the object pointed to be ws. This function is
not affected by locale and all wchar_t values are treated identically.
The null wide-character and wchar_t values not corresponding to valid
characters are not treated specially.
If n is 0, ws must be a valid pointer and the function behaves as if
no valid occurrence of wc is found.
RETURN VALUES
The wmemchr() function returns a pointer to the located wide-charac‐
ter, or a null pointer if the wide-character does not occur in the
object.
ERRORS
No errors are defined.
