NAME

JSGetAxisCoeffNZ - Axis value retrieving

SYNTAX

#include <jsw.h>

double JSGetAxisCoeffNZ(
        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 JSGetAxisCoeffNZ function fetches the last updated value of the specified axis n on the jsd structure.

RETURN VALUE

The JSGetAxisCoeffNZ function returns the coefficient value of the joystick axis number in a range of -1.0 to 1.0 or exactly 0.0 if the axis is within its null zone (if it has a null zone). The return value also does not make a distinction between success or error (error as if the axis was not valid).
