Parameters

`HwDeviceExtension`

[in] Pointer to the miniport's device extension.

`ProcessorIndex`

[in] A system-wide processor index. If a multiprocessor system contains a total of n logical processors, valid processor indexes range from 0 to n-1.

`MessageInterruptID`

[out] Pointer to a ULONG value in which the message interrupt ID of ProcessorIndex is written.

Return value

StorPortGetMessageInterruptIDFromProcessorIndex returns STOR_STATUS_SUCCESS if the miniport data is successfully reported. Possible error return values include the following.

Return code	Description
STOR_STATUS_INVALID_PARAMETER	There is an invalid parameter, such as an invalid ProcessorIndex value.
STOR_STATUS_UNSUCCESSFUL	An error occurred for internal reasons.
