Member Function Documentation

void ACE_POSIX_CB_Proactor::aio_completion_func (  sigval_t    cb_data )  [static]

ssize_t ACE_POSIX_CB_Proactor::allocate_aio_slot (  ACE_POSIX_Asynch_Result *    result )  [protected, virtual]

Find free slot to store result and aiocb pointer. Reimplemented from ACE_POSIX_AIOCB_Proactor.

virtual Proactor_Type ACE_POSIX_CB_Proactor::get_impl_type (  void    )  [virtual]

Reimplemented from ACE_POSIX_AIOCB_Proactor.

int ACE_POSIX_CB_Proactor::handle_events (  void    )  [protected, virtual]

Block indefinitely until at least one event is dispatched. Dispatch a single set of events. If <wait_time> elapses before any events occur, return 0. Return 1 on success i.e., when a completion is dispatched, non-zero (-1) on errors and errno is set accordingly. Reimplemented from ACE_POSIX_AIOCB_Proactor.

int ACE_POSIX_CB_Proactor::handle_events (  ACE_Time_Value &    wait_time )  [protected, virtual]

Dispatch a single set of events. If <wait_time> elapses before any events occur, return 0. Return 1 on success i.e., when a completion is dispatched, non-zero (-1) on errors and errno is set accordingly. Reimplemented from ACE_POSIX_AIOCB_Proactor.

int ACE_POSIX_CB_Proactor::handle_events_i (  u_long    milli_seconds )  [protected]

Dispatch a single set of events. If <milli_seconds> elapses before any events occur, return 0. Return 1 if a completion is dispatched. Return -1 on errors. Reimplemented from ACE_POSIX_AIOCB_Proactor.

int ACE_POSIX_CB_Proactor::notify_completion (  int    sig_num )  [protected, virtual]

Notify queue of "post_completed" ACE_POSIX_Asynch_Results called from post_completion method Reimplemented from ACE_POSIX_AIOCB_Proactor.
