Hey all,
Quite a specific question, but I was wondering if anyone has had any problems getting the first signal to be caught in a consumer-producer relationship with multiple consumers (HTTP web server)
for(i = 0; i < num_threads; i++) { pthread_cond...

Existing sequence: numRequests++; pthread_cond_signal(&condVars[nextWorker]);

I feel changing the order of incrementing 'numRequests' in producer will ensure the consumer will not miss the first signal .

I was told that in Java, unchecked exceptions can be caught in a try block, but if it's caught, isn't it called a checked exception?

Unchecked are exceptions that need to be caught in a try - catch block.

In tools/exceptions, I've set the option that the debugger stops when an exception is thrown. Whether it is caught or not .
How do I exclude an exception of that rule? Somewhere in my code there is a caught exception that is part of the program logic....

From here you can check/uncheck the exceptions you want.
Go to Debug > Exceptions and fold out the relevant branch .
In Visual Studio you can specify exactly which exceptions you want to halt on .

Is there a way to determine the exception type even know you caught the exception with a catch all?
Example:
try { SomeBigFunction(); } catch(...) { //Determine exception type here }

Once you had the exception instance, you would have to use a type inspection algorithm .
I do not believe there is a standard way of doing this .
Doing so would at the very least require you to be able to access the current exception .

I recently made the statement to a colleague that:
NullReferenceExceptions should never be explicitly caught
I used the word never.... hmmm. I've never seen a appropriate use case myself for catching them but I wanted to check if anyone else has?
Never...

NullReferenceExceptions should never be explicitly caught if you own the code which thrown the Exception

This may seem like a programming 101 question and I had thought I knew the answer but now find myself needing to double check. In this piece of code below, will the exception thrown in the first catch block then be caught by the general Exception catch...

Each Exception is caught only when inside a try block.
It won't be caught by the second catch block.

API doc says never catch Throwable subclass Error which signifies abnormal behavior. Does it implies that the segregation between Error and Exception is to tell programmers that which subclass should be caught and which shouldn't ? Or there is more to...

Yes, I think your analysis is correct here - you are not supposed to catch Error s because they represent runtime errors that can not be recovered from, such as OutOfMemoryError .

In C++, what is the difference between the following examples?
Re-throw pointer :
catch (CException* ex) { throw ex; }
Simple re-throw :
catch (CException* ex) { throw; }
When the re-throw is caught, will the stack trace be different?

In the second case, you are just letting the original object go up in the call stack (and thus preserving ... .
It looks like you generated the exception yourself in the throw ex line .
Basically, you are throwing the object yourself in the first case .

With Google Map v2, I would like to be able to trigger a function when clicking a text in the InfoWindow of a GMarker.

As far as I know, GMaps injects content into the InfoWindow programatically, so any bound event handlers on the injected elements will not fire unless you use event delegation:
$(".foo").live("click", myFunction);
See the live event handlers .
