rpc_port_number
The rpc_port_number procedure is used to read/modify the TCP port used by
the RPC server.
struct Rpc_Port_Parms {
unsigned
int
action;
unsigned
int
port;
};
struct Rpc_Port_Resp {
unsigned
int
error;
unsigned int port;
};
Rpc_Port_Resp rpc_port_number (Rpc_Port_Parms) = 2;
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 port value must be within the range of 0x0001 and 0xFFFF. An error of
5 is returned and the RPC Port value is unchanged if the port value is outside
of this range.
The returned Rpc_Port_Resp structure will always contain the current RPC
Port value, irrespective of the error value.
