| | 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); |
|
| |
The wmemchr() function locates the first occurrence
of wc in the initial 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.
|
| |
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.
