Calling convention --- what is it?

[Sriniv]

Hello all C-eers!
I've heard oc calling convention. What is it really? I've seen some
prefix words before function definitions. __stdcall, WINAPI, to name a
few. What are these? Are they platform specific? Does the grmmar of
standard C accomodates the snytaxes?

Thanks.

These things are not defined by the C Standard.

<OT>
usually, "calling convention" refers to how the implementation passes
the function parameters, and who cleans up afterwards.

There was a gay dog from Ontario
Who fancied himself a Lothario.
At a wench's glance
He'd snatch off his pants
And make for her Mons Venerio.
