Question

Sigiloso · Accepted Answer

Use a counting semaphore, incrementing each time a producer puts a new item in the queue and decrementing each time a consumer removes an item from the queue.

jetjeet · Answer

use three binarySemaphore/SemaphoreMutex(both are same)
empty
full
access

producer()
{
 wait(empty)
 wait(access)
    // Fill the q
 signal(access)
 signal(full)
}

consumer()
{
 wait(full)
 wait(access)
  // Consume the q
 signal(access)
 signal(empty)
}

Note : Use signal NOT broadcast when using POSIX cond_wait if you know what i mean.
