What's a callback?

John Larkin wrote in message

A few programmers I've known have used the term "callback", which
somehow related to executing a deferred subroutine or something. Does
anybody know anything about this term or its conventions? If I google
it, I just get a lot of telephone-type references.

I'm doing a thing now where, in an interrupt service routine, if I
think I'm out of time I set a flag to remind me to finish some chores
next time or so. I'm not sure if that qualifies as a "callback."

You need to search for "API" or "SDK" or "Win32" e.g.

And does it really matter what it is called, as long as it gets the
job done? :)

P.S. check out http://www.masm32.com/ - you can make a complete
window with less source than C and an executable filesize of 1k (The
PE header minimum size.) MASM32 incorporates many HLL features and
even type-checking, making assembler practical for both Win32 and DOS
programming.

This is most interesting. My Visual Studio 6 doesn't have MASM
(ml.exe) and every time I checked msdn, it suggested it did or that
I could still get it. I found out it's in the DDK and never
bothered. NASM was real cool and I could use it's object modules in
Visual Stooodio.

But the info at your link just tickles the hell out of me. Steve
Gibson - www.grc.com has a an article and win32 skeletons in ASM and
now the MASM project has included skeletons for this.

Thanks for the xmas present ;) Have a good one.
