|
ACT associated with the operation.
Reimplemented from ACE_WIN32_Asynch_Result. Reimplemented in ACE_WIN32_Asynch_Read_File_Result. |
|
The number of bytes which were requested at the start of the asynchronous read. Implements ACE_Asynch_Read_Stream_Result_Impl. Reimplemented in ACE_WIN32_Asynch_Read_File_Result. |
|
Number of bytes transferred by the operation.
Reimplemented from ACE_WIN32_Asynch_Result. Reimplemented in ACE_WIN32_Asynch_Read_File_Result. |
|
Proactor will call this method when the read completes.
Implements ACE_Asynch_Result_Impl. Reimplemented in ACE_WIN32_Asynch_Read_File_Result. |
|
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. Reimplemented from ACE_WIN32_Asynch_Result. Reimplemented in ACE_WIN32_Asynch_Read_File_Result. |
|
Error value if the operation fail.
Reimplemented from ACE_WIN32_Asynch_Result. Reimplemented in ACE_WIN32_Asynch_Read_File_Result. |
