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

(
