C.5 confi g_port_number
The confi g_port_number procedure is used to read/modify the TCP port
used by the Edevice confi guration channel.
struct Confi g_Port_Parms {
unsigned int action;
unsigned int port;
};
struct Confi g_Port_Resp {
unsigned int error;
unsigned int port;
};
Confi g_Port_Resp confi g_port_number (Confi g_Port_Parms) = 5;
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 port value must be within the range of 0x0001 and 0xFFFF. An error
of 5 is returned and the VXI-11 Abort Port value is unchanged if the port
value is outside of this range.
The returned Confi gt_Port_Resp structure will always contain the current
VXI-11 Abort Port value, irrespective of the error value.
