XGetPointerControl()XGetPointerControl()Name
XGetPointerControl – get the current pointer preferences.
Synopsis
XGetPointerControl(display, accel_numerator_return,
accel_denominator_return, threshold_return)
Display *display;
int *accel_numerator_return, *accel_denominator_return;
int *threshold_return;
Arguments
display Specifies a connection to an X server; returned from
XOpenDisplay().
accel_numerator_return
Returns the numerator for the acceleration multiplier.
accel_denominator_return
Returns the denominator for the acceleration multiplier.
threshold_return
Returns the acceleration threshold in pixels. The pointer
must move more than this amount before acceleration takes
effect.
DescriptionXGetPointerControl() gets the pointer's current acceleration parame‐
ters.
accel_numerator_return divided by accel_denominator_return is the num‐
ber of pixels the cursor moves per unit of motion of the pointer,
applied only to the amount of movement over threshold_return.
