Member Function Documentation

void ThreadGrp::add_thread ( int, Thread * )

Assigns a Thread object to each thread. If 0 is assigned to a thread, then that thread will be skipped.

ThreadGrp * ThreadGrp::clone ( int nthread = -1 ) [virtual]

Create a ThreadGrp like the current one. If nthread is given it will be the number of threads in the new group. If nthread is -1, the number of threads in the current group will be used. If cloning is not supported 0 will be returned. Reimplemented in PthreadThreadGrp.

int ThreadGrp::start_threads ( ) [pure virtual]

Starts the threads running. Thread 0 will be run by the thread that calls start_threads. Reimplemented in PthreadThreadGrp, PumaThreadGrp, and ProcThreadGrp.

int ThreadGrp::wait_threads ( ) [pure virtual]

Wait for all the threads to complete. This must be called before start_threads is called again or the object is destroyed. Reimplemented in PthreadThreadGrp, PumaThreadGrp, and ProcThreadGrp.
