can you please explain to me what this line of code means? it is in a .h file.
Also, please metion (if you have something to add) about the sizes of the variables. ie: 8, 16 or 32 bit. (To give some background info, I am porting code from a 16bit to a 32 bit processor, and I need to know if this line needs to be changed.
(Please focus on explaining the code though, then I can probably figure the rest out.
