wmemchr(3C)              Standard C Library Functions              wmemchr(3C)

NAME
       wmemchr - 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-character,
       or a null pointer if the wide-character does not occur in the object.

ERRORS
       No errors are defined.
