NAME

JSGetAxisCoeff - Axis value retrieving

SYNTAX

#include <jsw.h>

double JSGetAxisCoeff(

        js_data_struct *jsd,

        int n
)

ARGUMENTS

jsd
Specifies the pointer to the joystick data structure, which should have been set up by a prior call to JSInit.
n
Specifies the axis number.

DESCRIPTION

The JSGetAxisCoeff function fetches the last updated value of the specified axis n on the jsd structure.

RETURN VALUE

The JSGetAxisCoeff function returns the coefficient value of the joystick axis number in a range of -1.0 to 1.0 but does not take into account if the axis is currently within its null zone. The return value also does not make a distinction between success or error (error as if the axis was not valid).
