NAME
JSGetAttributesList - Joystick device attribute retrieving
SYNTAX
#include <jsw.h>
js_attribute_struct *JSGetAttributesList(
int *total,
const char *calibration
)
typedef struct {
char *name; /* Descriptive name. */
char *device_name; /* Device name. */
/* Specifies that this joystick device
* is configured and calibrated properly.
*/
int is_configured;
/* If true then suggests device may
* already be opened.
*/
int is_in_use;
/* Device may not disconnected at the
* moment, turned off, or driver not
* loaded.
*/
int not_accessable;
} js_attribute_struct;
ARGUMENTS
- total
- Specifies the pointer to a int return value for the total number of device attributes loaded.
- calibration
- Specifies the calibration file.
DESCRIPTION
The JSGetAttributesList function fetches attributes for all joysticks accessable (not just configured/calibrated) on the system. Regardless if the joystick is already initialized, in use, or available.
If calibration is NULL then some values may be set to 0 or NULL in the attrib structure (ie members is_configured and name).
RETURN VALUE
The JSGetAttributesList function returns a pointer to a list of js_attribute_struct structures, the number of items indicated by the value set to total.
The returned list needs to be deallocated with a call to JSFreeAttributesList(3).
