The rationale behind the change in the history for this is because is that he/she wanted to "unmarshal". However, in functions like WlanConnect(), it is used as an "input". So, it needs to be marshaled. Then I believe they should be IntPtr.

Return the Input Panel button to its visible state.

Hide the Input Panel button.

A request to display the input panel. Any pending SIP_DOWN requests are ignored.

A request to hide the input panel. When this value is used, a timer is set and the input panel is lowered only after the timer message is received. This approach prevents the input panel from flashing when one control requests SIP_DOWN and another control immediately requests SIP_UP.

forces the input panel to be hidden immediately, without setting a timer. If you want the input panel hidden and are sure there will be no SIP_UP requests — for example, because your application is a full-screen game — use this value.

tells the system to ignore any pending down requests. That is, if SHSipPreference is called with the SIP_DOWN flag, the system sets a timer and after the timer fires, the input panel is lowered. However, if you call SIP_UNCHANGED before the timer fires, then the input panel will stay in its current location.

InputReportByteLength

Specifies the maximum size, in bytes, of all the input reports (including the report ID, if report IDs are used, which is prepended to the report data).

NumberInputButtonCaps

Specifies the number of input HIDP_BUTTON_CAPS structures that HidP_GetButtonCaps returns.

NumberInputValueCaps

Specifies the number of input HIDP_VALUE_CAPS structures that HidP_GetValueCaps returns.

NumberInputDataIndices

Specifies the number of data indices assigned to buttons and values in all input reports.

Callers of the HIDClass support routines use the information provided in this structure when a called routine requires, as input, the size of a report type, the number of link collection nodes, the number of control capabilities, or the number of data indices.

• Use Marshal.StringToCoTaskMemUni() to prepare input parameters (IntPtr) declared to receive strings.
An IntPtr is a pointer to a memory location (unmanaged) that adapts to the platform it is running on (64-bit, etc.) UNLIKE a standard int/Integer. You should always use this type for unmanaged calls that require it, even though an int will appear to work on your development machine.
