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)
protectedvirtual

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)
protectedvirtual

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.
