rpc_use_family(3ncs)
Name
rpc_use_family − create a socket of a specified address family for a remote procedure call (RPC) server (server only)
Syntax
#include <idl/c/rpc.h>
void rpc_$use_family(family, sockaddr, slength, status)
unsigned long family;
socket_$addr_t *sockaddr;
unsigned long *slength;
status_$t *status;
Arguments
family The address family of the socket to be created. The value must be one of socket_$internet or socket_$unspec.
sockaddr The socket address of the socket on which the server will listen.
slength The length, in bytes, of sockaddr.
status The completion status. If the completion status returned in status.all is equal to status_$ok , then the routine that supplied it was successful.
Description
The rpc_$use_family routine creates a socket for a server without specifying its port number. The RPC runtime software assigns a port number. If a server must listen on a particular well-known port, use rpc_$use_family_wk to create the socket.
A server listens on one socket per address family, regardless of how many interfaces that it exports. Therefore, servers should make this call once per supported address family.
Examples
The following statement creates a server’s socket:
rpc_$use_family (family, &saddr, &slen, &status);
Diagnostics
This section lists status codes for errors returned by this rpc_$ routine in status.all.
rpc_$cant_create_sock
The RPC runtime library was unable to create a socket.
rpc_$not_in_call An internal error.
rpc_$proto_error An internal protocol error.
rpc_$too_many_sockets
The server is trying to use more than the maximum number of sockets that is allowed; it has called rpc_$use_family or rpc_$use_family_wk too many times.
rpc_$addr_in_use
The address and port specified in an rpc_$use_family_wk routine are already in use. This is caused by multiple calls to rpc_$use_family_wk with the same well-known port.
