Include mouse cursor in screen capture

Question

I use CreateDC / BitBlt / GetDIBits etc. to capture the screen, but the cursor is not captured. Is there some simple argument or something to have it included?

#include <Windows.h>
#include <stdio.h>
#include <assert.h>

void scrshot() {
    HWND hwnd = GetDesktopWindow();
    HDC hdc = GetWindowDC(hwnd);
    HDC hdcMem = CreateCompatibleDC(hdc);
    int cx = GetDeviceCaps(hdc, HORZRES);
    int cy = GetDeviceCaps(hdc, VERTRES);
    HBITMAP hbitmap(NULL);
    hbitmap = CreateCompatibleBitmap(hdc, cx, cy);
    SelectObject(hdcMem, hbitmap);
    BitBlt(hdcMem, 0, 0, cx, cy, hdc, 0, 0, SRCCOPY);
    CURSORINFO cursor = { sizeof(cursor) };
    GetCursorInfo(&cursor);
    if (cursor.flags == CURSOR_SHOWING) {
        RECT rect;
        GetWindowRect(hwnd, &rect);
        ICONINFO info = { sizeof(info) };
        GetIconInfo(cursor.hCursor, &info);
        const int x = cursor.ptScreenPos.x - rect.left - rect.left - info.xHotspot;
        const int y = cursor.ptScreenPos.y - rect.top - rect.top - info.yHotspot;
        BITMAP bmpCursor = { 0 };
        GetObject(info.hbmColor, sizeof(bmpCursor), &bmpCursor);
        DrawIconEx(hdcMem, x, y, cursor.hCursor, bmpCursor.bmWidth, bmpCursor.bmHeight,
            0, NULL, DI_NORMAL);
    }
}

int main(){
    scrshot();
    return 0;
}
