std::wmemset
From cppreference.com
Defined in header
<cwchar>
|
||
wchar_t* wmemset( wchar_t* dest, wchar_t ch, std::size_t count );
|
||
Copies wide character ch
into each of the first count
wide characters of the object pointed to by dest
. If the object is not trivially-copyable (e.g., scalar, array, or a C-compatible struct), the behavior is undefined. If dest+size+1 points outside the object, the behavior is undefined.
