man JSGetAxisCoeffNZ (Fonctions bibliothèques) - Axis value retrieving
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).
