CLoadDirectDraw::LoadDirectDraw
A version of this page is also available for
4/8/2010
Loads and initializes the DirectDraw library in the specified area.
Syntax
HRESULT LoadDirectDraw(
LPSTR szDevice
);
Parameters
- szDevice
This parameter is optional; if omitted, this method loads DirectDraw to the base drawing area.
Return Value
Returns S_OK if DirectDraw loaded correctly or E_NOINTERFACE otherwise.
Remarks
DirectDraw is not always available, so applications cannot statically link to the library. Therefore, this member function loads the library, gets the function entry point addresses, and calls them to create the driver objects.
Call this member function before calling CLoadDirectDraw::GetDirectDraw to retrieve the IDirectDraw interface.
