Is it possible to go through multiple cases in one case like this? how?
switch(foo)
{
case 1 or 2:
dosomething(); break; //dosomething if foo is either 1 or 2
case 3:
dosomethingelse (); break; // dosomethingelse if foo is 3
}

Remember that if there's no 'break' on a 'case
clause', execution falls through to the next.
So just 'stack' case values which should do
the same thing, as above.
-Mike You are missing a C book that explains how the swicth statment works, and
what a break statement does. Notice that there is no break after case 1:.
Hence, when foo is equal to 1, bar will be called.
Sinan.
Oh, thanks! BTW I have the K&R C book but my friend is borrowing it.

I'm alittle confused now.
Looking at that piece of code it looks like in case 1 nothing is done
and to access bar() it would require that foo = 2
What am I missing?
case 1:
// nothing to do here, continue to next statement
case 2:
Only a 'break' statement after case '1' and before
case '2' will cause case '2' to be skipped.

The case doesn't close until it's broken.
Just like detective work. :-)

I have a thread that does periodic database maintenance. While this
process is going on I would like the rest of the application to hold

Any ideas on what the best way for me to determine when the thread is

Hello,
One of my internet providers has blocked my broadband adsl internet
connection for over a 2 months now. They still steal money from my bank
account and they still hold the adsl line hostage, so I can switch over
to another ADSL internet provider. I could switch over to a (tv) cable
internet provider, however these are more expensive and only few
providers available because of mergers.
I am not happy about all this:
