POFFLINE_ROUTINE callback function (resapi.h)

Marks a resource as unavailable for use after cleanup processing is complete. The POFFLINE_ROUTINE type defines a pointer to this function.

Syntax

POFFLINE_ROUTINE PofflineRoutine;

DWORD PofflineRoutine(
  [in] RESID Resource
)
{...}

[in] Resource

Resource identifier for the resource to be taken offline.

Return code/value	Description
ERROR_SUCCESS 0	The request completed successfully, and the resource is offline.
ERROR_IO_PENDING 997 (0x3E5)	The request is still pending, and a thread has been activated to process the offline request.

If the operation was not successful for other reasons, Offline should return one of the system error codes.

If Offline returns an error code other than ERROR_IO_PENDING, the Resource Monitor logs an event and calls Terminate.

For effective implementation strategies of the Offline entry-point function, see Implementing Offline.
