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   )

Do the transmission. All the info to do the transmission is in the <result> member.
