socket_equal(3ncs)														socket_equal(3ncs)

Name
       socket_equal - compare two socket addresses

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

       boolean socket_$equal(sockaddr1, s1length, sockaddr2, s2length, flags,			      status)
       socket_$addr_t *sockaddr1;
       unsigned long s1length;
       socket_$addr_t *sockaddr2;
       unsigned long s2length;
       unsigned long flags;
       status_$t *status;

Arguments
       sockaddr1	   A socket address.  The socket address is the structure returned by either or

       s1length 	   The length, in bytes, of sockaddr1.

       sockaddr2	   A socket address.  The socket address is the structure returned by either or

       s2length 	   The length, in bytes, of sockaddr2.

       flags		   The logical OR of values selected from the following:

			   socket_$eq_hostid   Indicates that the host IDs are to be compared.

			   socket_$eq_netaddr  Indicates that the network addresses are to be compared.

			   socket_$eq_port     Indicates that the port numbers are to be compared.

			   socket_$eq_network  Indicates that the network IDs are to be compared.

       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 compares two socket addresses.  The flags parameter determines which fields of the socket addresses	are  compared.	 The  call
       returns `true' (not zero) if all of the fields compared are equal, `false' (zero) if not.

Examples
       The following routine compares the network and host IDs in the socket addresses sockaddr1 and sockaddr2:
       if (socket_$equal (&sockaddr1, s1length, &sockaddr2, s2length,
	       socket_$eq_network | socket_$eq_hostid, &status))
       printf ("sockaddrs have equal network and host IDs
");

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.
