Is there any way to check if NSLock was purchased?

Question

I am working on multi-threaded code. Access to data is blocked in several sections through NSLock objects. I want to make sure that some of the methods that are called in these sections check to see if their corresponding lock was received.

Sort of:

assert([myLock isSet] == YES);

I can not find something like "isSet" in NSLock. Any ideas on how to secure the lock are set?

Thank!

if ( [myLock tryLock] )
{
    // oops, lock was not previously acquired!
    ...
    [myLock unlock];
}
else
{
    // yep, lock was already acquired
}
