.SH NAME
LIBAXL_REQUEST_GET_POINTER_CONTROL - Get current acceleration and threshold for the pointer
.SH SYNOPSIS
.nf
#include <libaxl.h>

#define LIBAXL_REQUEST_GET_POINTER_CONTROL 106
struct libaxl_request_get_pointer_control {
        uint8_t  \fIopcode\fP;
        uint8_t  \fI__pad\fP;
        uint16_t \fI_request_length\fP;

.SH DESCRIPTION
The display server shall return the current
acceleration and threshold for the pointer.
.PP
The value of the
.I opcode
field shall be
.I LIBAXL_REQUEST_GET_POINTER_CONTROL
to signify that the request is of the
request described in this document.
.PP
Other fields are filled in automatically by the
.BR libaxl_send_request (3)
function.
.SH ERRORS
None.

.PP
The display server shall, unless it returns an
error, return one
.B "struct libaxl_reply_get_pointer_control"
with the
.I acceleration_numerator
and
.I acceleration_denominator
fields set such that
.I ((double)acceleration_numerator/acceleration_denominator)
is the value of the current acceleration for the pointer,
and the
.I threshold
field set to the current threshold for the pointer.
