Check the documentation for ACE_Asynch_Operation::cancel.

ACE_HANDLE  handle,
const void *  completion_key,
ACE_Proactor *  proactor = 0
)  [virtual]
 

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.

ACE_HANDLE ACE_POSIX_Asynch_Operation::handle_ [protected]
 

I/O handle used for reading.

ACE_POSIX_Proactor* ACE_POSIX_Asynch_Operation::posix_proactor_ [protected]
 

It is easy to get this specific implementation proactor here, since it is the one that creates the correct POSIX_Asynch_* objects. We can use this to get to the implementation proactor directly.
