## Detailed Description

This class provides concrete implementation for <ace_asynch_write_file> for POSIX platforms where the completion strategy for Proactor is based on AIOCB (AIO Control Blocks).

## Constructor & Destructor Documentation

ACE_POSIX_Asynch_Write_File::ACE_POSIX_Asynch_Write_File | ( | ACE_POSIX_Proactor * | posix_proactor | ) |

| Constructor.

ACE_POSIX_Asynch_Write_File::~ACE_POSIX_Asynch_Write_File | ( | void |  | ) | `[virtual]`

| Destructor.

## Member Function Documentation

int ACE_POSIX_Asynch_Write_File::write | ( | ACE_Message_Block & | message_block,
|  | size_t | bytes_to_write,
|  | const void * | act,
|  | int | priority,
|  | int | signal_number = `0`
| ) | `[private, virtual]`

| This <write> belongs to ACE_POSIX_Asynch_Write_Stream. We have put this here to avoid compiler warnings. We forward this method call to the <ACE_POSIX_Asynch_Write_Stream::write> one. Implements ACE_Asynch_Write_File_Impl.

int ACE_POSIX_Asynch_Write_File::write | ( | ACE_Message_Block & | message_block,
|  | size_t | bytes_to_write,
|  | u_long | offset,
|  | u_long | offset_high,
|  | const void * | act,
|  | int | priority,
|  | int | signal_number = `0`
| ) | `[virtual]`

| This starts off an asynchronous write. Upto <bytes_to_write> will be written and stored in the <message_block>. The write will start at <offset> from the beginning of the file. Implements ACE_Asynch_Write_File_Impl.
