socket_valid_families(3ncs)											       socket_valid_families(3ncs)

       socket_valid_families - obtain a list of valid address families

       #include <idl/c/socket.h>

       void socket_$valid_families(max_families, families, status)
       unsigned long *max_families;
       socket_$addr_family_t families[ ];
       status_$t *status;

       max_families	   The maximum number of families that can be returned.

       families[ ]	   An array of socket_$addr_family_t.  Possible values for this type are enumerated in Currently, only ip is supported for

       status		   The completion status.  This variable is set if the families[ ] array is not long enough to hold all  the  valid  fami-
			   lies. If the completion status returned in is equal to status_$ok , then the routine that supplied it was successful.

       The routine returns a list of the address families that are valid on the calling host.

       The following routine returns the valid address family:
       socket_$valid_families (1, &families, $status);

       slength		   The length, in bytes, of sockaddr.

       name		   A  string in the format family:host[port], where family is the address family and host is the host name; host may be in
			   the standard numeric form (for example, # if a textual host name cannot be obtained.  Currently, only  ip	is
			   supported for family.

       nlength		   On input, the maximum length, in bytes, of the name to be returned.	On output, the actual length of the name returned.

       port		   The port number.

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

       The routine converts a socket address to a textual address family, host name, and port number.
