/* A simple, asynchronous, lock-free (if requested also wait-free)
|
|
* queue. Not multiple-reader/multiple-writer safe. If that is
|
|
* required both sides can be protected by a mutex each. --- Which is
|
|
* not a bad thing in most cases, since this queue is intended for
|
|
* communication between a normal thread and a single real-time
|
|
* thread. Only the real-time side needs to be lock-free/wait-free.
|
|
*
|
|
* If the queue is full and another entry shall be pushed, or when the
|
|
* queue is empty and another entry shall be popped and the "wait"
|
|
* argument is non-zero, the queue will block on a UNIX FIFO object --
|
|
* that will probably require locking on the kernel side -- which
|
|
* however is probably not problematic, because we do it only on
|
|
* starvation or overload in which case we have to block anyway. */
