ATOM type?

[C#er]

What is the ATOM type?
I find that an ATOM is a WORD, which that is an unsigned short.
But when I use this type?
I would like a good explanation about this type..


Thanks

You can find the definition as well as the atom usage in MSDN (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/dataexchange/atoms.asp).
See also the return value from RegisterClass (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/windowing/windowclasses/windowclassreference/windowclassfunctions/registerclass.asp) / RegisterClassEx function.
