Constructor & Destructor Documentation

ACE_POSIX_Asynch_Transmit_Handler::ACE_POSIX_Asynch_Transmit_Handler ACE_POSIX_Proactor posix_proactor,
ACE_POSIX_Asynch_Transmit_File_Result result
 

Constructor. Result pointer will have all the information to do the file transmission (socket, file, application handler, bytes to write).

ACE_POSIX_Asynch_Transmit_Handler::~ACE_POSIX_Asynch_Transmit_Handler void   )  [virtual]
 

Destructor.


Member Function Documentation

void ACE_POSIX_Asynch_Transmit_Handler::handle_read_file const ACE_Asynch_Read_File::Result result  )  [protected, virtual]
 

This is called when asynchronous reads from the file complete.

Reimplemented from ACE_Handler.

void ACE_POSIX_Asynch_Transmit_Handler::handle_write_stream const ACE_Asynch_Write_Stream::Result result  )  [protected, virtual]
 

This is called when asynchronous writes from the socket complete.

Reimplemented from ACE_Handler.

int ACE_POSIX_Asynch_Transmit_Handler::initiate_read_file void   )  [protected]
 

Issue asynch read from the file.

int ACE_POSIX_Asynch_Transmit_Handler::transmit void   )
