Detailed Description

Simplistic posix thread class.

To create a threaded object derive from this class and implement the run member function. Check as often as you can the m_run member variable and immediately return from the function if it is set to false.

Yes, I know that there are numerous libraries that do the same and better. But I find it essential to keep the dependencies as low as possible for thin clients.

Member Function Documentation

void Thread::quit (   )

Forcibly stop thread. Not recommended as this might leak resources Definition at line 52 of file thread.cpp.

virtual void Thread::run (   )  [protected, pure virtual]

The thread mainloop. This pure virtual function has to be implemented by the thread. Put your mainloop in here. Frequently check the m_run flag. If false immediately return. See also: m_run running Implemented in DMMClass, Escort97, GDM703, M9803R, MetexAscii, PeakTech10Ascii, and VC820. Referenced by start_thread().

bool Thread::running (   )  const [inline]

Is the thread running? Definition at line 62 of file thread.h. References m_run.

int Thread::start (   )

Start the thread. Returns: pthread_create return code Definition at line 39 of file thread.cpp. References m_pthread, m_run, and start_thread(). Referenced by MetexAscii::MetexAscii(), MetexAscii::run(), and GDM703::run().

void * Thread::start_thread (  void *   )  [static, private]

pthreads need a "C" compatible function pointer. This static function wraps the class member run. Definition at line 30 of file thread.cpp. References run(). Referenced by start().

void Thread::stop (   )  [inline]

Gracefully stop the thread. Definition at line 54 of file thread.h. References m_run.

void Thread::wait (   )

Wait for the thread to finish (no timeout!). Definition at line 47 of file thread.cpp. References m_pthread.
