NAME

       XkbSetDeviceButtonActions - Change only the button actions for an input extension device

SYNOPSIS

       Bool  XkbSetDeviceButtonActions  (Display  *dpy,  XkbDeviceInfoPtr  device,  unsigned  int  first_button,
              unsigned int num_buttons);

ARGUMENTS

       dpy    connection to X server

       device structure defining the device and modifications

       first_button
              number of first button to update, 0 relative

       num_buttons
              number of buttons to update

DESCRIPTION

       XkbSetDeviceButtonActions   assigns   actions   to   the   buttons   of   the   device    specified    in
       device_info->device_spec.   Actions  are  assigned to num_buttons buttons beginning with first_button and
       are taken from the actions specified in device_info->btn_acts.

       If  the  server  does  not  support  assignment   of   Xkb   actions   to   extension   device   buttons,
       XkbSetDeviceButtonActions  has  no  effect  and  returns  False.  If  the  device  has  no  buttons or if
       first_button  or  num_buttons  specify  buttons  outside  of   the   valid   range   as   determined   by
       device_info->num_btns, the function has no effect and returns False. Otherwise, XkbSetDeviceButtonActions
       sends a request to the server to change the actions for the specified buttons and returns True.

       If the actual request sent to the server involved illegal button numbers, a BadValue  protocol  error  is
       generated.  If  an  invalid  device  identifier  is  specified in device_info->device_spec, a BadKeyboard
       protocol error results. If the actual device  specified  in  device_info->device_spec  does  not  contain
       buttons and a request affecting buttons is made, a BadMatch protocol error is generated.

DIAGNOSTICS

       BadKeyboard    The device specified was not a valid core or input extension device

       BadMatch       A  compatible  version  of  Xkb was not available in the server or an argument has correct
                      type and range, but is otherwise invalid

       BadValue       An argument is out of range
