## Detailed Description

Auxillary handler for doing <Asynch_Transmit_File> in Unix. <ACE_POSIX_Asynch_Transmit_File> internally uses this.

This is a helper class for implementing <ACE_POSIX_Asynch_Transmit_File> in Unix systems.

## Member Enumeration Documentation

enum ACE_POSIX_Asynch_Transmit_Handler::ACT`[protected]`

  | Enumeration values:
  HEADER_ACT |
  DATA_ACT |
  TRAILER_ACT |

## 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.
