C.13 gpib_address
The gpib_address procedure is used to read/modify the Edevice GPIB bus
address.
struct Gpib_Addr_Parms {
unsigned
int
action;
unsigned
int
address;
};
struct Gpib_Addr_Resp {
unsigned
int
error;
unsigned
int
address;
};
Gpib_Addr_Resp gpib_address (Gpib_Addr_Parms) = 13;
The action value determines whether the client wishes to execute a read of
the current setting, or a modifi cation 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 re-
turned.
If the RPC message is of insuffi cient length to satisfy the required length,
an error value of 1 is returned.
The address must be within the range of 0 and 30. An error of 5 is returned
and the current GPIB address is unchanged if address is determined to be
invalid.
The returned Gpib_Addr_Resp structure will always contain the current
Edevice GPIB bus address, irrespective of the error value.
