Detailed Description

DetachedThread is a Thread that detaches in the constructor. join() is not used. The object is usually created with new. The default destroy() deletes it when the entry returns. Override run() for the thread entry, or pass a function pointer.

Constructor & Destructor Documentation

DetachedThread()

DetachedThread ( )

protected

Constructs a thread object to execute the virtual method run() when start() is called. DetachedThreads are always destructed by the virtual method destroy(). If objects of this class are created by new, destroy() must be overloaded ti call delete.

Member Function Documentation

destroy()

virtual void destroy ( )

protectedvirtual

This method is called after the thread has finished. The default implementation uses delete to destruct this object.

run()

virtual void run ( )

protectedvirtual

This method is executed in a separate thread once start() is called. Override this method to implement a thread.

init()

void init ( const Callable< void > & cb )

inherited

The callable cb will be used as the thread entry. If another thread entry was set previously it will be replaced.

start()

void start ( )

inherited

This starts the execution of the thread by calling the thread entry. Throws a SystemError on failure.

exit()

void exit ( )

staticinherited

This function is meant to be called from within a thread to leave the thread at once. Implicitly called when the thread entry is left. Throws a SystemError on failure.

yield()

void yield ( )

staticinherited

This function is meant to be called from within a thread to give up the CPU to other threads. Throws a SystemError on failure.

sleep()

void sleep ( unsigned int ms )

staticinherited

The calling thread sleeps for ms milliseconds. Throws a SystemError on failure.
