struct input_absinfo {
__s32 value;
__s32 minimum;
__s32 maximum;
__s32 fuzz;
__s32 flat;
__s32 resolution;
}; latest reported value for the axis.
specifies minimum value for the axis.
specifies maximum value for the axis.
specifies fuzz value that is used to filter noise from the event stream.
values that are within this value will be discarded by joydev interface and reported as 0 instead.
specifies resolution for the values reported for the axis.
Note that input core does not clamp reported values to the [minimum, maximum] limits, such task is left to userspace.
Resolution for main axes (ABS_X, ABS_Y, ABS_Z) is reported in units per millimeter (units/mm), resolution for rotational axes (ABS_RX, ABS_RY, ABS_RZ) is reported in units per radian.
