124/// ioctl: "get abs value/limits"
125///
126/// `abs` should be one of the "Absolute axes" values defined in the Linux kernel headers.
127/// In modern (5.11) kernels these are in `include/uapi/linux/input-event-codes.h`, and in older
128/// kernels these defines can be found in `include/uapi/linux/input.h`
129///
130/// # Panics
131///
132/// Calling this with a value greater than the kernel-defined `ABS_MAX` (typically 0x3f) will panic.
133///
134/// # Safety
135///
136/// 'abs' must be a valid axis number and supported by the device, otherwise the behavior is
137/// undefined.
