       pointer


SYNTAX

       XChangePointerControl(display, do_accel, do_threshold,
       accel_numerator,
                               accel_denominator, threshold)
             Display *display;
             Bool do_accel, do_threshold;
             int accel_numerator, accel_denominator;
             int threshold;

       XGetPointerControl(display, accel_numerator_return,
       accel_denominator_return,
                              threshold_return)
             Display *display;
             int *accel_numerator_return,
       *accel_denominator_return;
             int *threshold_return;


ARGUMENTS

       accel_denominator
                 Specifies the denominator for the acceleration
                 multiplier.

       accel_denominator_return
                 Returns the denominator for the acceleration
                 multiplier.

       accel_numerator
                 Specifies the numerator for the acceleration
                 multiplier.

       accel_numerator_return
                 Returns the numerator for the acceleration mul-
                 tiplier.

       display   Specifies the connection to the X server.

       do_accel  Specifies a Boolean value that controls whether
                 the values for the accel_numerator or
                 accel_denominator are used.

       do_threshold
                 Specifies a Boolean value that controls whether
                 the value for the threshold is used.

       threshold Specifies the acceleration threshold.

       threshold_return
                 Returns the acceleration threshold.

       nator argument.

       XChangePointerControl can generate a BadValue error.

       The XGetPointerControl function returns the pointer's cur-
       rent acceleration multiplier and acceleration threshold.


DIAGNOSTICS

       BadValue  Some numeric value falls outside the range of
                 values accepted by the request.  Unless a spe-
                 cific range is specified for an argument, the
                 full range defined by the argument's type is
                 accepted.  Any argument defined as a set of
                 alternatives can generate this error.
