Re: help me.

Responding to Wu...

thanks for your reply.
In fact, above source code is just like goto statement, when you want
to do something, your assign the "state" variable to some value. the
"exit" flag will be set
after certain state is reached or the "quit" signal reach. this method
is really bad. Not only the code is like a mess, but sometimes the
modification of share memory will lost. I think the better solution
will be some kind of message(signal etc) instead of poll sharememory.
but now I only have rights to modify the control panel. so what I can
do is make this block of source code more readable.

I assume one of the DoSomeX operations would set the exit flag. You could deal with that without a global flag by substituting

while (TRUE)
{
if (GetAState())
if (!DoSomeA()) break;
if (GetCState())
if (!DoSomeC()) break;
...
}

in my proposal.

There is nothing wrong with me that could
not be cured by a capful of Drano.
