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.

Parameters

dest - pointer to the object to fill
ch - fill byte
count - number of bytes to fill

Return value

dest

Example

#include <iostream>
#include <cwchar>
 
int main()
{
    int a[20];
    std::memset(a, 0, sizeof(a));
    std::cout << "a[0] = " << a[0] << '\n';
}

Output:

a[0] = 0
