multithreading class [modified]

[es1968]

Hi, I need help to write a multi thread simple class, I know this should be simple but I face some difficulties, any help will be appreciated. Implementing single-write, multiple-read multi thread synchronization (using windows synchronization primitives like mutex, semaphore etc.). Thanks in advance, Eyal

Hi Moak, Just faced with this question in a C++ questioner/quiz. I read information/tutorials on multithreading mutex but I haven't deal yet with the answer. looking for the right answer. Best, Eyal

There are many ways to do this, depending on if you want to enforce a preference for readers or writers or neither. The easy way would be to assume the target system is Vista or greater and use the new SRWLOCK[^] variable. :) However, I expect the spirit of the question was to write the logic yourself. Check the following links: http://blogs.msdn.com/vancem/archive/2006/03/28/563180.aspx[^] http://blogs.msdn.com/vancem/attachment/563180.ashx[^] http://www.bluebytesoftware.com/blog/2009/01/30/ASinglewordReaderwriterSpinLock.aspx[^] If you have a question about a specific implimentation then post the code you having troubles with.
