Member Function Documentation

virtual void PosixThread::OnDisconnect (  void   )  [inline, protected, virtual]

A derived method to call when a SIGPIPE is being delivered to a specific thread.

virtual void PosixThread::OnException (  void   )  [inline, protected, virtual]

A derived method to call when a SIGABRT is being delivered to a specific thread.

virtual void PosixThread::OnHangup (  void   )  [inline, protected, virtual]

A derived method to handle hangup events being delivered to a specific thread.

virtual void PosixThread::OnPolling (  void   )  [inline, protected, virtual]

A derived method to handle asynchronous I/O requests delivered to the specified thread.

virtual void PosixThread::OnSignal (  int   signo )  [inline, protected, virtual]

A derivable method to call for delivering a signal event to a specified thread. Parameters: signo   posix signal id.

virtual void PosixThread::OnTimer (  void   )  [inline, protected, virtual]

A derivable method to call when a SIGALRM is being delivered to a specific thread.

void PosixThread::SignalMain (  signo_t   signo )  [inline, protected]

In the Posix version of Common C++, this can be used to send a signal into the main application thread. Parameters: signo   a posix signal id.

void PosixThread::SignalParent (  signo_t   signo )  [inline, protected]

In the Posix version of Common C++, this can be used to send a signal into the parent thread of the current object. Parameters: signo   a posix signal id.

void PosixThread::SignalThread (  int   signo )  [inline]

Delivers a Posix signal to the current thread. Parameters: signo   a posix signal id.

void PosixThread::WaitSignal (  signo_t   signo )  [protected]

Used to wait on a Posix signal from another thread. This can be used as a crude rondevious/synchronization method between threads. Parameters: signo   a posix signal id.

void PosixThread::endTimer (  void   )  [protected]

Terminates the timer before the timeout period has expired. This prevents the timer from sending it's SIGALRM and makes the timer available to other threads.

timeout_t PosixThread::getTimer (  void   )  [protected]

Gets the time remaining for the current threads timer before it expires. Returns: time remaining before timer expires in milliseconds.

void PosixThread::setSignal (  int   signo, bool   mode )  [protected]

Used to enable or disable a signal within the current thread. Parameters: signo   posix signal id. active   set to true to enable.

void PosixThread::setTimer (  timeout_t   timer )  [protected]

Used to specify a timeout event that can be delivered to the current thread via SIGALRM. When the timer expires, the OnTimer() method is called for the thread. At present, only one thread timer can be active at any given time. On some operating systems (including Linux) a timer can be active on each thread. Parameters: timer   timeout in milliseconds.
