rpc_name_to_sockaddr

rpc_name_to_sockaddr(3ncs) rpc_name_to_sockaddr(3ncs)

Name
rpc_name_to_sockaddr - convert a host name and port number to a socket address (client or server)

Syntax
#include <idl/c/rpc.h>

void rpc_$name_to_sockaddr(name, nlength, port, family, sockaddr, slength, status)
unsigned char name;
unsigned long nlength;
unsigned long port;
unsigned long family;
socket_$addr_t *sockaddr;
unsigned long *slength;
status_$t *status;

Arguments
name A string that contains a host name and, optionally, a port and an address family. The format is family:host[port],
where family: and [port] are optional. If you specify a family as part of the name parameter, you must specify
socket_$unspec in the family parameter. The family part of the name parameter is ip; host is the host name; port is an
integer port number.

nlength The number of characters in name.

port The socket port number. This parameter should have the value rpc_$unbound_port if you are not specifying a well-known
port; in this case, the returned socket address will specify the Local Location Broker (LLB) forwarding port at host.
If you specify the port number in the name parameter, this parameter is ignored.

family The address family to use for the socket address. This value corresponds to the communications protocol used to access
the socket and determines how the sockaddr is expressed. If you specify the address family in the name parameter, this
parameter must have the value socket_$unspec.

sockaddr The socket address corresponding to name, port, and family.

slength The length, in bytes, of sockaddr.

status The completion status. If the completion status returned in is equal to status_$ok , then the routine that supplied it
was successful.

Description
The routine provides the socket address for a socket, given the host name, the port number, and the address family.

You can specify the socket address information either as one text string in the name parameter or by passing each of the three elements as
separate parameters( name, port, and family ); in the latter case, the name parameter should contain only the hostname.

Diagnostics
This section lists status codes for errors returned by this routine in

rpc_$not_in_call An internal error.

rpc_$proto_error An internal protocol error. This routine has been superseded by the routine.
