Hello. I have the following problem: I have one writter and many readers. The writter writes in a buffer and the readers read from this buffer. It's not classicle producer/consumers, because all the readers need to read all the data that the writter has written. I implemented it using read/write lock: Write lock for writting and read lock for reading. The problem is that when there's no data to be read I must use busywait or sleepwait. If condition variables worked with read/write locks it would be easy: Every write sygnals, if the reader has read all the data it blocks on condition variable... but no, there isn't condition variable for read/write locks. So my question is: Is there any way to avoid sleepwait with some mechanism given the situation? I must not use mutexes, because there are many many readers. Thanks
