Function Documentation

XN_C_API XnStatus XN_C_DECL xnGetDeviceName	(	XnNodeHandle	hInstance,
		XnChar *	strBuffer,
		XnUInt32 *	pnBufferSize
	)

Gets the device name.

Parameters:

hInstance	[in] A handle to the instance.
strBuffer	[in] A buffer to accept the device name.
pnBufferSize	[in/out] Size of the buffer.

Returns:

XN_STATUS_OK if succeeded, or XN_STATUS_OUTPUT_BUFFER_OVERFLOW if buffer is not sufficient. in such a case, the device name should be truncated to fit in the buffer, and pnBufferSize should be updated to the required size.

XN_C_API XnStatus XN_C_DECL xnGetSerialNumber	(	XnNodeHandle	hInstance,
		XnChar *	strBuffer,
		XnUInt32 *	pnBufferSize
	)

Gets the serial number of the device.

Parameters:

hInstance	[in] A handle to the instance.
strBuffer	[in] A buffer to accept the string.
pnBufferSize	[in/out] Size of the buffer.

Returns:

XN_STATUS_OK if succeeded, or XN_STATUS_OUTPUT_BUFFER_OVERFLOW if buffer is not sufficient. in such a case, the string should be truncated to fit in the buffer, and pnBufferSize should be updated to the required size.

XN_C_API XnStatus XN_C_DECL xnGetVendorSpecificData	(	XnNodeHandle	hInstance,
		XnChar *	strBuffer,
		XnUInt32 *	pnBufferSize
	)

Gets a vendor-specific string.

Parameters:

hInstance	[in] A handle to the instance.
strBuffer	[in] A buffer to accept the string.
pnBufferSize	[in/out] Size of the buffer.

Returns:

XN_STATUS_OK if succeeded, or XN_STATUS_OUTPUT_BUFFER_OVERFLOW if buffer is not sufficient. in such a case, the string should be truncated to fit in the buffer, and pnBufferSize should be updated to the required size.
