GetDIBits function Null safety gdi32

int GetDIBits (
  1. int hdc,
  2. int hbm,
  3. int start,
  4. int cLines,
  5. Pointer<NativeType> lpvBits,
  6. Pointer<BITMAPINFO> lpbmi,
  7. int usage
)

The GetDIBits function retrieves the bits of the specified compatible bitmap and copies them into a buffer as a DIB using the specified format.

int GetDIBits(
  HDC          hdc,
  HBITMAP      hbm,
  UINT         start,
  UINT         cLines,
  LPVOID       lpvBits,
  LPBITMAPINFO lpbmi,
  UINT         usage
);
