**EntryPoint
35 Loads a PE/COFF image into memory, this is not follow the original purpose of
36 PeCoffGetEntryPoint library class. But it's ok that Unix package not run on a real
37 platform and this is for source level debug.
41 Pe32Data - Pointer to a PE/COFF Image
43 EntryPoint - Pointer to the entry point of the PE/COFF image

80 Returns the machine type of PE/COFF image.

82 The reason is NT32 package needs to load the image to memory to support source
