syscall: ashet.overlapped.await_completion_of
Documentation
Awaits one or more explicit asynchronous operations and returns the
number of events elements.
The kernel will only await elements provided in events and all of those events must
not be awaited by another await_completion_of.
When the function returns, events will have all completed events unchanged, and all
unfinished events set to null. This way, a simple check via index can be done instead of
the need for iteration of events to find what was finished.
Note:
This syscall will always return as soon as a single event has finished.
Note:
It is invalid to await the same operation with two concurrent calls to await_completion_of.
Note:
Elements awaited with this function will be guaranteed to not be returned by
another concurrent call to await_completion.
Note:
For blocking operations, this function will suspend the current thread until the request has been completed.
