Re: Synchronize the read/write operation between threads
You could have a read-only routine that doesn't use a critical section, but
it's often dangerous to do even though since the circumstances of the data
may change even for reading (I.E., data gets deleted from an array or
changes position).

The design seems safe but inefficient. All the writer and reader threads
must use the critical section, which suspends them to avoid simultaneous
access, so they are sometimes slowed down.
Scott, this seems to be a single writer, multiple reader problem. Using
the critical section means that only one reader has access at a time, when
theoretically multiple readers could be accessing simultaneously. Only
the writer needs to have mutual exclusion. I'm not sure how to implement
this using critical sections. Any idea?
