RI_KEY_E1 RI_KEY_E1 Functions

Enumerates the raw input devices attached to the system.

An array of structures for the devices attached to the system. If null, the number of devices are returned in *puiNumDevices.

If pRawInputDeviceList is null, the function populates this variable with the number of devices attached to the system; otherwise, this variable specifies the number of structures that can be contained in the buffer to which pRawInputDeviceList points. If this value is less than the number of devices attached to the system, the function returns the actual number of devices in this variable and fails with .

The size of a structure, in bytes.

If the function is successful, the return value is the number of devices stored in the buffer pointed to by pRawInputDeviceList.

On any other error, the function returns (UINT) -1 and GetLastError returns the error indication.

The devices returned from this function are the mouse, the keyboard, and other Human Interface Device (HID) devices.

To get more detailed information about the attached devices, call GetRawInputDeviceInfo using the hDevice from .

ms645598 unsigned int GetRawInputDeviceList([Out, Buffer, Optional] RAWINPUTDEVICELIST* pRawInputDeviceList,[InOut] unsigned int* puiNumDevices,[In] unsigned int cbSize) GetRawInputDeviceList

Retrieves the information about the raw input devices for the current application.

An array of structures for the application.

The number of structures in *pRawInputDevices.

The size, in bytes, of a structure.

If successful, the function returns a non-negative number that is the number of structures written to the buffer.

If the pRawInputDevices buffer is too small or null, the function sets the last error as , returns -1, and sets puiNumDevices to the required number of devices. If the function fails for any other reason, it returns -1. For more details, call GetLastError.

To receive raw input from a device, an application must register it by using RegisterRawInputDevices.

ms645599 unsigned int GetRegisteredRawInputDevices([Out, Buffer, Optional] RAWINPUTDEVICE* pRawInputDevices,[InOut] unsigned int* puiNumDevices,[In] unsigned int cbSize) GetRegisteredRawInputDevices

Retrieves information about the raw input device.

A handle to the raw input device. This comes from the lParam of the WM_INPUT message, from the hDevice member of , or from GetRawInputDeviceList. It can also be null if an application inserts input data, for example, by using SendInput.

Specifies what data will be returned in pData. This parameter can be one of the following values.

ValueMeaning
0x20000007

pData points to a string that contains the device name.

For this uiCommand only, the value in pcbSize is the character count (not the byte count).

0x2000000b

pData points to an structure.

0x20000005

pData points to the previously parsed data.

?

A reference to a buffer that contains the information specified by uiCommand. If uiCommand is , set the cbSize member of to sizeof() before calling GetRawInputDeviceInfo.

The size, in bytes, of the data in pData.

If successful, this function returns a non-negative number indicating the number of bytes copied to pData.

If pData is not large enough for the data, the function returns -1. If pData is null, the function returns a value of zero. In both of these cases, pcbSize is set to the minimum size required for the pData buffer.

Call GetLastError to identify any other errors.

 ms645597 unsigned int GetRawInputDeviceInfoW([In, Optional] void* hDevice,[In] RAW_INPUT_DEVICE_INFO_TYPE uiCommand,[Out, Buffer, Optional] void* pData,[InOut] unsigned int* pcbSize) GetRawInputDeviceInfoW

Retrieves the raw input from the specified device.

A handle to the structure. This comes from the lParam in WM_INPUT.

The command flag. This parameter can be one of the following values.

ValueMeaning
0x10000005

Get the header information from the structure.

0x10000003

Get the raw data from the structure.

?

A reference to the data that comes from the structure. This depends on the value of uiCommand. If pData is null, the required size of the buffer is returned in *pcbSize.

The size, in bytes, of the data in pData.

The size, in bytes, of the structure.

If pData is null and the function is successful, the return value is 0. If pData is not null and the function is successful, the return value is the number of bytes copied into pData.

If there is an error, the return value is (UINT)-1.

GetRawInputData gets the raw input one structure at a time. In contrast, GetRawInputBuffer gets an array of structures.

 ms645596 unsigned int GetRawInputData([In] HRAWINPUT hRawInput,[In] RAW_INPUT_DATA_TYPE uiCommand,[Out, Buffer, Optional] void* pData,[InOut] unsigned int* pcbSize,[In] unsigned int cbSizeHeader) GetRawInputData

Registers the devices that supply the raw input data.

An array of structures that represent the devices that supply the raw input.

The number of structures pointed to by pRawInputDevices.

The size, in bytes, of a structure.

TRUE if the function succeeds; otherwise, . If the function fails, call GetLastError for more information.

To receive WM_INPUT messages, an application must first register the raw input devices using RegisterRawInputDevices. By default, an application does not receive raw input.

To receive WM_INPUT_DEVICE_CHANGE messages, an application must specify the flag for each device class that is specified by the usUsagePage and usUsage fields of the structure . By default, an application does not receive WM_INPUT_DEVICE_CHANGE notifications for raw input device arrival and removal.

If a structure has the flag set and the hwndTarget parameter is not set to null, then parameter validation will fail.

ms645600 BOOL RegisterRawInputDevices([In, Buffer] const RAWINPUTDEVICE* pRawInputDevices,[In] unsigned int uiNumDevices,[In] unsigned int cbSize) RegisterRawInputDevices

Performs a buffered read of the raw input data.

A reference to a buffer of structures that contain the raw input data. If null, the minimum required buffer, in bytes, is returned in *pcbSize.

The size, in bytes, of a structure.

The size, in bytes, of the structure.

If pData is null and the function is successful, the return value is zero. If pData is not null and the function is successful, the return value is the number of structures written to pData.

If an error occurs, the return value is (UINT)-1. Call GetLastError for the error code.

Using GetRawInputBuffer, the raw input data is buffered in the array of structures. For an unbuffered read, use the GetMessage function to read in the raw input data.

The NEXTRAWINPUTBLOCK macro allows an application to traverse an array of structures.

Note??To get the correct size of the raw input buffer, do not use *pcbSize, use *pcbSize * 8 instead. To ensure GetRawInputBuffer behaves properly on WOW64, you must align the structure by 8 bytes. The following code shows how to align for WOW64. 

[StructLayout(LayoutKind.Explicit)]	
            internal struct 	
            { [FieldOffset(0)] public  header; [FieldOffset(16+8)] public  mouse; [FieldOffset(16+8)] public  keyboard; [FieldOffset(16+8)] public  hid;
