3When IN HDC is not NULL
41. we need check the IN HDC is NULL or not
52. if it not null we need create a directdraw handler
6   and store it to pDirectDrawGlobal->hDD
73. if the directdraw handle is null return false
8   we did fail to create directdraw HAL
94. if the directdraw handle was not null we return true
10   we did susses to create directdraw HAL
11
12When IN HDC is NULL
13Now we come to if IN HDC is null basic we need create
14   a hdc and cashe some data
151. if internal cache of directdraw handle is not null (pDirectDrawGlobalInternal->hDD)
16   we take it and fill to the public directdraw handler (pDirectDrawGlobal->hDD)
17   and return susses.
18
192.  if no internal cache of directdraw handle is found we need create it
20    by using CreateDC for tempary HDC that will be cache in the win32k later
21
223.  we need check see if we got a tempary HDC or not, if we fail getting tempary
23    HDC return FALSE
24
254. Now we trying create directdraw handler it being cache to (pDirectDrawGlobalInternal->hDD)
26   and it also set same handler to the public (pDirectDrawGlobal->hDD)
275. if it fails to create directdraw handle return false
28   we did fail to create directdraw HAL
296. if it susses create directdraw handle return true
30   we did susses to create directdraw HAL
31
32To create a directdraw handler you need call the NtGdiDdCreateDirectDrawObject with a hdc
