##### Remarks

This function will unsubscribe from a specific input event based on the given hash (you can retrieve the input event hashes using [`SimConnect_EnumerateInputEvents`](simconnect-enumerateinputevents/)). You may also supply 0 (null) as the hash value, in which case you will be unsubscribing from *all* input events. The function generates no response event.
