| Return code | Description |
|---|---|
| STOR_STATUS_SUCCESS | The specified MSI-X interrupt was successfully enabled/disabled. |

A miniport can call StorPortMaskMsixInterrupt to mask or unmask the specified interrupt in the MSI-X hardware interrupt table. If a table entry is masked, the device does not generate interrupts that correspond to that table entry.
