inputSyncCallback
Input callback function to be implemented by a subclass.
Declaration
virtual void inputSyncCallback(
UInt32token );Parameters
- token:
A 32-bit token value that can be used by convention to communicate from user space to the stream. The semantics of this value are defined by the IOStream subclass.
Overview
The inputSyncCallback() method is called as a result of a fast trap from user space. It is called on the same thread as the user request, so no context switch is necessary.
