Long Pointer to Double WORD

[Hammurabi]

LP is from the days when there were both "long" pointers and short pointers (something to do with memory segmentation).

DWORD is from the days when a "word" was 16 bits, so a "double word" would be 32.

WinAPI is full of "legacy" garbage like that. Combined with the despicable "Hungarian" notation, it really sucks.

[decoupling]

Legacy of old version windows.

At 32bit version, Long Pointer == Pointer == 32bit address.
