They are points within your program at which it is guaranteed that
everything that should have happened (and in particular all the side
effects) up till this point /has/ happened (or won't ever happen!). You get
them at the end of expression statements, and at various other places as
well.

any pointers to some resource which explains them in detail will be of
much help...

See "C: A Reference Manual", by Harbison & Steele. My 4th edition carries a
reasonable explanation on p83, and again on pages 228-229.

Or, alternatively, OP can get the "from the horse's mouth" explanation
from 5.1.2.3, subparagraph 2, in the draft n869 standard. (OP can,
presumably, use Google to locate this document.)

Yes, but ISO Standards tend to make lousy tutorials.

Yes, but ISO Standards tend to make lousy tutorials.

I've always found ISO 8859-1 quite understandable.

There is now a link to a copy of it on the CLC wiki. I used the way back
machine to find Dan Pop's copy and uploaded it to my site. If Dan
objects (which I think is unlikely) I can remove it. Links to that and
other versions of the standard are here http://clc-wiki.net/wiki/c_standard

P.S. Anyone know how Dan is doing?

Where is Dan Pop when you need him?

I've asked a few times and heard zip-a-dee-doo-dah. Seems ominous.

Nah.

Lawrence dropped out for a couple of years, then popped up out of nowhere
for a few months, and has since vanished again. (I hope he'll be back
soon.) I dropped out for well over a year, and then re-materialised. Chris
D disappeared for a while, but has returned. We hardly ever see Steve
nowadays, but just occasionally, he sticks his head round the door to see
what's going on.

It happens. I'm sure Dan is fine.

I've been considering starting a rumor of his death.

But it's a valid C expression, assuming appropriate declarations for
zip, a, dee, doo, and dah.

Long may it be greatly exaggerated.

But not much plot -- I think that was left to a graphics standards
committee.
