This PR adds Win32 event support for IOCP driver. Win32 event is kind of foundamental syncronize object. It could be, e.g., an event handle, an input console handle, a pipe handle, or a mutex handle.
Win32 event could not be polled by IOCP, but IOCP could be waited as a usual event on Windows 10+.
MsgWaitForMultipleObjectsExis used here to wait them all, and reserves possibility for APC routines and window messages. If there are more than 62 events to be waited, the remain events will be waited in seperate threads.In this PR, stdio is also refactored to use the new feature. To make the code simpler, the console code page is forced to UTF8.
This PR is a prediction of the planned
compio-process. We need the feature to wait for the process handle.
