man XSetDeviceValuators (Fonctions bibliothèques) - initialize the valuators on an extension input device
NAME
XSetDeviceValuators - initialize the valuators on an extension input device
SYNTAX
XSetDeviceValuators(display, device, valuators, first_valuator, num_valuators)
Display *display;
XDevice *device;
int *valuators;
int first_valuator;
int num_valuators;
ARGUMENTS
- display
- Specifies the connection to the X server.
- device
- Specifies the device whose valuators are to be initialized.
- valuators
- Specifies a pointer to an array of integer values to be used to initialize the device valuators.
- first_valuator
- Specifies the first valuator to be set. Valuators are numbered beginning with zero.
- num_valuators
- Specifies the number of valuators to be set.
DESCRIPTION
The XSetDeviceValuators request sets the current values of the valuators of an input device. The valuators in the range first_valuator to (first_valuator + num_valuators) are set to the specified values. Valuators are numbered beginning with 0. Not all input devices support initialization of valuator values. If this request is made to a device that does not support valuators initialization, a BadMatch error will occur.
If the request succeeds, a status of Success is returned. If another client has the device grabbed, a status of AlreadyGrabbed is returned.
XSetDeviceValuators can generate a BadLength, BadDevice , BadMatch, or BadValue error.
DIAGNOSTICS
- BadDevice
- An invalid device was specified. The specified device does not exist or has not been opened by this client via XOpenInputDevice.
- BadMatch
- This error may occur if an XSetDeviceValuators request is made specifying a device that has no valuators and reports no axes of motion, or if such a request is made specifying a device that does not support valuator initialization.
- BadValue
- An invalid first_valuator or num_valuators values was specified.
