## Detailed Description

This class abstracts out the common things needed for implementing <Asynch_Operation> for POSIX platforms. Specific implementations such as <POSIX_AIOCB_Asynch_Operation> can derive from this class.

## Constructor & Destructor Documentation

ACE_POSIX_Asynch_Operation::ACE_POSIX_Asynch_Operation | ( | void |  | ) | `[protected]`

| No op contructor.

ACE_POSIX_Asynch_Operation::~ACE_POSIX_Asynch_Operation | ( | void |  | ) | `[protected, virtual]`

| Destructor.

## Member Function Documentation

int ACE_POSIX_Asynch_Operation::cancel | ( | void |  | ) |

| Check the documentation for <ACE_Asynch_Operation::cancel>. Reimplemented in ACE_POSIX_AIOCB_Asynch_Read_Stream, ACE_POSIX_AIOCB_Asynch_Write_Stream, ACE_POSIX_AIOCB_Asynch_Read_File, ACE_POSIX_AIOCB_Asynch_Write_File, ACE_POSIX_Asynch_Accept, ACE_POSIX_AIOCB_Asynch_Transmit_File, ACE_POSIX_AIOCB_Asynch_Read_Dgram, and ACE_POSIX_AIOCB_Asynch_Write_Dgram.

int ACE_POSIX_Asynch_Operation::open | ( | ACE_Handler & | handler,
|  | ACE_HANDLE | handle,
|  | const void * | completion_key,
|  | ACE_Proactor * | proactor = 0
| ) |

| Initializes the factory with information which will be used with each asynchronous call. If (<handle> == ACE_INVALID_HANDLE), <ACE_Handler::handle> will be called on the <handler> to get the correct handle. No need for the Proactor since the sub classes will know the correct implementation Proactor class, since this Operation class itself was created by the correct implementation Proactor class. Reimplemented in ACE_POSIX_AIOCB_Asynch_Read_Stream, ACE_POSIX_AIOCB_Asynch_Write_Stream, ACE_POSIX_AIOCB_Asynch_Read_File, ACE_POSIX_AIOCB_Asynch_Write_File, ACE_POSIX_Asynch_Accept, ACE_POSIX_AIOCB_Asynch_Transmit_File, ACE_POSIX_AIOCB_Asynch_Read_Dgram, and ACE_POSIX_AIOCB_Asynch_Write_Dgram.

ACE_Proactor * ACE_POSIX_Asynch_Operation::proactor | ( | void |  | ) | const

| Return the underlying proactor. Reimplemented in ACE_POSIX_AIOCB_Asynch_Read_Stream, ACE_POSIX_AIOCB_Asynch_Write_Stream, ACE_POSIX_AIOCB_Asynch_Read_File, ACE_POSIX_AIOCB_Asynch_Write_File, ACE_POSIX_Asynch_Accept, ACE_POSIX_AIOCB_Asynch_Transmit_File, ACE_POSIX_AIOCB_Asynch_Read_Dgram, and ACE_POSIX_AIOCB_Asynch_Write_Dgram.
