int ACE_Proactor::post_wakeup_completions ( int how_many ) [static, protected]
 

Post <how_many> completions to the completion port so that all threads can wake up. This is used in conjunction with the <run_event_loop>.

int ACE_Proactor::register_handle ( ACE_HANDLE handle,
const void * completion_key ) [virtual]
 

This method adds the <handle> to the I/O completion port. This function is a no-op function for Unix systems and returns 0;.

Resets the static so that the <run_event_loop> method can be restarted.

int ACE_Proactor::run_event_loop ( ACE_Time_Value & tv ) [static]
 

Run the event loop until the method returns -1, the <end_event_loop> method is invoked, or the expires.

int ACE_Proactor::run_event_loop ( void ) [static]

long ACE_Proactor::schedule_timer ( ACE_Handler & handler,
const void * act,
const ACE_Time_Value & time ) [virtual]
 

Schedule a <handler> that will expire after <time>. If it expires then is passed in as the value to the <handler>'s <handle_timeout> callback method. This method returns a <timer_id>. This <timer_id> can be used to cancel a timer before it expires. The cancellation ensures that <timer_ids> are unique up to values of greater than 2 billion timers. As long as timers don't stay around longer than this there should be no problems with accidentally deleting the wrong timer. Returns -1 on failure (which is guaranteed never to be a valid <timer_id>).

void ACE_Proactor::timer_queue ( TIMER_QUEUE * tq )
 

TIMER_QUEUE * ACE_Proactor::timer_queue ( void ) const
 

Get/Set timer queue.

int ACE_Proactor::wake_up_dispatch_threads ( void )
