XskNotifySocket function

The purpose of this API is two-fold:

  1. Pokes the underlying driver to continue IO processing
  2. Waits on the underlying driver until IO is available

Syntax

typedef
HRESULT
XSK_NOTIFY_SOCKET_FN(
    _In_ HANDLE Socket,
    _In_ XSK_NOTIFY_FLAGS Flags,
    _In_ UINT32 WaitTimeoutMilliseconds,
    _Out_ XSK_NOTIFY_RESULT_FLAGS *Result
    );

Parameters

Flags

One or more XSK_NOTIFY_FLAGS flags.

TODO

Remarks

Apps will commonly need to perform both of these actions at once, so a single API is offered to handle both in a single syscall. When performing both actions, the poke is executed first. If the poke fails, the API ignores the wait and returns immediately with a failure result. If the poke succeeds, then the wait is executed. The wait timeout interval can be set to INFINITE to specify that the wait will not time out.
