I'm working on a problem which we have to use semaphores to solve. I have an array which contains two semaphores, gsem, and given certain conditions call sem_wait(&(gsem[me])), which is supposed to waiting until that particular process is woken up. However, for some reason it gives me the error Bad file descriptor. I looked up sem_wait and the Open Group spec says this is not an error sem_wait can cause. This is making my whole program crazy and I have no idea why this is failing.

Guaranteed semaphore order?

as seen on Stack Overflow - Search for 'Stack Overflow'
The documentation for the .NET Semaphore class states that: There is no guaranteed order, such as FIFO or LIFO, in which blocked threads enter the semaphore. In this case, if I want a guaranteed order (either FIFO or LIFO), what are my options? Is this something that just isn't easily possible… >>> More

I have created a "Manager" class that contains a limited set of resources. The resources are stored in the "Manager" as a Queue. I initialize the Queue and a Semaphore to the same size, using the semaphore to block a thread if there are no resources available. I have multiple threads calling into… >>> More

Using boost locks for RAII access to a semaphore

as seen on Stack Overflow - Search for 'Stack Overflow'
Suppose I write a C++ semaphore class with an interface that models the boost Lockable concept (i.e. lock(); unlock(); try_lock(); etc.). Is it safe/recommended to use boost locks for RAII access to such an object? In other words, do boost locks (and/or other related parts of the boost thread library)… >>> More
How can I replace this semaphore with a monitor?

as seen on Stack Overflow - Search for 'Stack Overflow'
Hi In previous question of mine, someone had meantioned that using Semaphores were expensive in C# compared to using a monitor. So I ask this, how can I replace the semaphore in this code with a monitor? I need function1 to return its value after function2 (in a separate thread) has been completed… >>> More
