join

Waits until this finishes, i.

e. the function func, as given to Thread, returns or exit is called. If this has already terminated, then join returns immediately.

Any thread can wait for any other thread by calling join, not just its 'creator'. Calling join from multiple threads for the same this leads to undefined behaviour.

The value returned by func or given to exit is returned by this function.

join consumes the reference to the passed-in this. This will usually cause the Thread struct and associated resources to be freed. Use g_thread_ref to obtain an extra reference if you want to keep the GThread alive beyond the join call.

Parameters:

this

a Thread

Returns:

the return value of the thread
