Detailed Description

An abstract class which adds information to the OVERLAPPED structure to make it more useful.

An abstract base class from which you can obtain some basic information like the number of bytes transferred, the ACT associated with the asynchronous operation, indication of success or failure, etc. Subclasses may want to store more information that is particular to the asynchronous operation it represents.

size_t ACE_WIN32_Asynch_Result::bytes_transferred ( void   )  const [virtual]
const void* ACE_WIN32_Asynch_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.

Implements ACE_Asynch_Result_Impl.
