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
_X_S_e_t_D_e_v_i_c_e_V_a_l_u_a_t_o_r_s
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 _B_a_d_M_a_t_c_h 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.
_X_S_e_t_D_e_v_i_c_e_V_a_l_u_a_t_o_r_s
can generate a _B_a_d_L_e_n_g_t_h, _B_a_d_D_e_v_i_c_e , _B_a_d_M_a_t_c_h, or
_B_a_d_V_a_l_u_e error.
DIAGNOSTICS
-
_B_a_d_D_e_v_i_c_e
-
An invalid device was specified. The specified device does not exist or has
not been opened by this client via _X_O_p_e_n_I_n_p_u_t_D_e_v_i_c_e.
-
_B_a_d_M_a_t_c_h
-
This error may occur if an _X_S_e_t_D_e_v_i_c_e_V_a_l_u_a_t_o_r_s 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.
-
_B_a_d_V_a_l_u_e
-
An invalid first_valuator or num_valuators values was specified.
