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).
