Detailed Description

A portable semaphore object, optimally including a realtime-safe 'post' operation.

Constructor & Destructor Documentation

Semaphore()

synthclone::Semaphore::Semaphore ( QObject *  parent = 0 )

explicit

Constructs a new Semaphore object.

Parameters

parent

The parent object of the semaphore.

~Semaphore()

synthclone::Semaphore::~Semaphore

(

)

Destroys a Semaphore object.

Member Function Documentation

post()

void synthclone::Semaphore::post

(

)

Increments the semaphore.

If there is one or more threads waiting on the semaphore, then a thread will be woken up.

Note

This operation is realtime-safe on UNIX, and probably realtime-safe on Mac. It's unknown whether the operation is realtime-safe on Windows.

wait()

void synthclone::Semaphore::wait

(

)

Decrements the semaphore if the semaphore's value is greater than zero; otherwise, the thread will wait until another thread performs a 'post' operation on the semaphore.
