This class has all the information necessary for the <handler> to uniquiely identify the completion of the asynchronous write.
This class differs slightly from ACE_Asynch_Write_Stream::Result as it calls back <ACE_Handler::handle_write_file> on the <handler> instead of <ACE_Handler::handle_write_stream>. No additional state is required by this class as ACE_Asynch_Result can store the <offset>.

Constructor is protected since creation is limited to ACE_Asynch_Write_File factory.

Destructor.

| size_t ACE_WIN32_Asynch_Write_File_Result::bytes_to_write | ( | void | ) | const [virtual] |
The number of bytes which were requested at the start of the asynchronous write.
Reimplemented from ACE_WIN32_Asynch_Write_Stream_Result.
| size_t ACE_WIN32_Asynch_Write_File_Result::bytes_transferred | ( | void | ) | const [virtual] |
Number of bytes transferred by the operation.

ACE_Proactor will call this method when the write completes.
Reimplemented from ACE_WIN32_Asynch_Write_Stream_Result.
| const void * ACE_WIN32_Asynch_Write_File_Result::completion_key | ( | void | ) | const [virtual] |
This returns the ACT associated with the handle when it was registered with the I/O completion port. This ACT is not the same as the ACT associated with the asynchronous operation.

| ACE_Message_Block & ACE_WIN32_Asynch_Write_File_Result::message_block | ( | void | ) | const [virtual] |
Message block that contains the data to be written.
Reimplemented from ACE_WIN32_Asynch_Write_Stream_Result.
| u_long ACE_WIN32_Asynch_Write_File_Result::offset | ( | void | ) | const [virtual] |
This really make sense only when doing file I/O.
Reimplemented from ACE_WIN32_Asynch_Write_Stream_Result.
| u_long ACE_WIN32_Asynch_Write_File_Result::offset_high | ( | void | ) | const [virtual] |

Reimplemented from ACE_WIN32_Asynch_Write_Stream_Result.
| int ACE_WIN32_Asynch_Write_File_Result::priority | ( | void | ) | const [virtual] |
The priority of the asynchronous operation. Currently, this is not supported on Win32.
