It doesn't connect to any +physical device, and it never delivers any events. It functions as +both a pointer and keyboard device, and may be used as X server's core +pointer and/or core keyboard. It's purpose is to allow the X server +to operate without a core pointer and/or core keyboard. +.SH CONFIGURATION DETAILS +Please refer to XF86Config(__filemansuffix__) for general configuration +details and for options that can be used with all input drivers. This +driver doesn't have any configuration options in addition to those. +.SH "SEE ALSO" +XFree86(1), XF86Config(__filemansuffix__), xf86config(1), Xserver(1), X(__miscmansuffix__). +.SH AUTHORS +Authors include... diff --git a/src/void.c b/src/void.c new file mode 100644 index 0000000..15cc38b --- /dev/null +++ b/src/void.c @@ -0,0 +1,288 @@ +/* + * Copyright 1999 by Frederic Lepied, France. <Lepied@XFree86.org> + * + * Permission to use, copy, modify, distribute, and sell this software and its + * documentation for any purpose is hereby granted without fee, provided that + * the above copyright notice appear in all copies and that both that + * copyright notice and this permission notice appear in supporting + * documentation, and that the name of Frederic Lepied not be used in + * advertising or publicity pertaining to distribution of the software without + * specific, written prior permission.
