C.14 system_controller
The system_controller procedure is used to read/modify the system controller
mode. If the system controller mode is set TRUE, then the Edevice will initial-
ize at boot time as the GPIB bus controller.
struct Sys_Control_Parms {
unsigned
int
action;
unsigned
int
controller;
};
struct Sys_Control_Resp {
unsigned
int
error;
unsigned
int
controller;
};
Sys_Control_Resp system_controller (Sys_Control_Parms) = 14;
The action value determines whether the client wishes to execute a read of the
current setting, or a modification of the current value.
action = 0 = read of current value
action = 1 = modify current value
If the action value is other than 0 or 1, then an error value of 5 is returned.
If the RPC message is of insufficient length to satisfy the required length, an
error value of 1 is returned.
The controller mode must be either 0 or 1. An error of 5 is returned and the
current system controller mode is unchanged if controller is determined to be
invalid.
The returned Sys_Control_Resp structure will always contain the current system
controller mode, irrespective of the error value.
