Member Function Documentation
virtual void sc::ThreadGrp::add_thread
(
int
threadnum ,
Thread *
thread ,
int
priority
)
[virtual]
Like add_thread(threadnum, thread), but assign a priority that the thread is to use.
The member is primarily for experimentation, the priority argument is currently not well defined and ignored.
Reimplemented in sc::PthreadThreadGrp .
virtual void sc::ThreadGrp::add_thread
(
int
threadnum ,
Thread *
thread
)
[virtual]
Assigns a Thread object to each thread.
If 0 is assigned to a thread, then that thread will be skipped.
Reimplemented in sc::PthreadThreadGrp .
virtual ThreadGrp* sc::ThreadGrp::clone
(
int
nthread = -1
)
[virtual]
Create a ThreadGrp like the current one.
If nthread is given, the new ThreadGrp will attempt to support that number of threads, but the actual number supported may be less. If nthread is -1, the number of threads in the current group will be used.
Reimplemented in sc::PthreadThreadGrp .
virtual int sc::ThreadGrp::start_threads
(
)
[pure virtual]
virtual int sc::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.
Implemented in sc::PthreadThreadGrp .
