XChangePointerControl(3) XLIB FUNCTIONS XChangePointerControl(3) NAME
XChangePointerControl, XGetPointerControl - control pointer SYNTAX
int XChangePointerControl(Display *display, Bool do_accel, Bool do_threshold, int accel_numerator, int accel_denominator, int threshold); int XGetPointerControl(Display *display, int *accel_numerator_return, int *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 multiplier. 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. DESCRIPTION
The XChangePointerControl function defines how the pointing device moves. The acceleration, expressed as a fraction, is a multiplier for movement. For example, specifying 3/1 means the pointer moves three times as fast as normal. The fraction may be rounded arbitrarily by the X server. Acceleration only takes effect if the pointer moves more than threshold pixels at once and only applies to the amount beyond the value in the threshold argument. Setting a value to -1 restores the default. The values of the do_accel and do_threshold arguments must be True for the pointer values to be set, or the parameters are unchanged. Negative values (other than -1) generate a BadValue error, as does a zero value for the accel_denominator argument. XChangePointerControl can generate a BadValue error. The XGetPointerControl function returns the pointer's current acceleration multiplier and acceleration threshold. DIAGNOSTICS
BadValue Some numeric value falls outside the range of values accepted by the request. Unless a specific range is specified for an argu- ment, the full range defined by the argument's type is accepted. Any argument defined as a set of alternatives can generate this error. SEE ALSO
