Sample X Input Device Extension Program

The functions described in this chapter allow client programs to access input devices other than the X keyboard and the X pointer.




	NOTE: The functions described in this chapter supersede many of the HP extension functions described in . You should use the functions described in this chapter unless you require functionality that is only supported through the HP extension functions. Do not mix functions of the two types. If you need to use input device extension functions, select either the X standard functions or the HP functions.

None of these features are required in order for the X server or X clients to operate correctly if the X keyboard and X pointer are the only input devices.

These input device extension functions are accessible through the library libXi.a. Defined constants and structures needed by clients that use these functions are found in the files XI.h and XInput.h.

X include files are installed in a subdirectory of /usr/include. For example, if the HP-UX Developer's Toolkit 1.0 product is installed, the X include files are installed in /usr/include/X11R5/X11.

Refer to the sample program at the end of this chapter for more information about using the functions described below.
