socket_from_name(3ncs) [ultrix man page]

socket_from_name(3ncs)													    socket_from_name(3ncs)

Name
       socket_from_name - convert a name and port number to a socket address

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

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

Arguments
       family The  integer  representation  of	an  address  family.   Value  can be socket_$internet or socket_$unspec If the family parameter is
	      socket_$unspec, then the name parameter is scanned for a prefix of family: (for example, ip:).

       name   A string in the format family:host[port], where family:, host, and [port] are all optional.  The family is an address  family.   The
	      only  valid  family  is  ip.   If  you specify a family as part of the name parameter, you must specify socket_$unspec in the family
	      parameter.  The host is a host name.  A leading number sign (#) can be used to indicate that  the  host  name  is  in  the  standard
	      numeric  form (for example, #192.9.8.7).	If host is omitted, the local host name is used.  The port is a port number.  If you spec-
	      ify a port as part of the name parameter, the port parameter is ignored.

       nlength
	      The length, in bytes, of name.

       port   A port number.  If you specify a port number in the name parameter, this parameter is ignored.

       sockaddr
	      A socket address.

       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  success-
	      ful.

Description
       The  routine converts a textual address family, host name, and port number to a socket address.	The address family and the port number can
       be either specified as separate parameters or included in the name parameter.

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.
