get HiByte [modifed]

[big_denny_200]

Hi again :) In windef.h we can see these defines :

#define LOBYTE(w) ((BYTE)((DWORD_PTR)(w) & 0xff))
#define HIBYTE(w) ((BYTE)((DWORD_PTR)(w) >> 8))

I don't understand how HIBYTE gets, most significant byte, by above code. With LOBYTE all is clear. I thought these macros were getting bytes from 32 bit value. It found out they are for 16 bit values, now all is clear thanks. -- modified at 14:36 Friday 19th May, 2006
