socket_valid_family(3ncs)												 socket_valid_family(3ncs)

Name
       socket_valid_family - check whether an address family is valid

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

       boolean socket_$valid_family(family, status)
       unsigned long family;
       fBstatus_$t *status;

Arguments
       family		   The integer representation of an address family.

       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 returns `true' if the specified address family is valid for the calling host, `false' if not valid.

Examples
       The following routine checks whether socket_$internet is a valid address family:
       internetvalid = socket_$valid_family(socket_$internet, &status);

socket_to_numeric_name(3ncs)											      socket_to_numeric_name(3ncs)

Name
       socket_to_numeric_name - convert a socket address to a numeric name and port number

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

       void socket_$to_numeric_name(sockaddr, slength, name, nlength, port,				   status

       socket_$addr_t *sockaddr;
       unsigned long slength;
       socket_$string_t name;
       unsigned long *nlength;
       unsigned long *port;
       status_$t *status;

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

       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 in the standard
			   numeric form (for example, #192.7.8.9 for an IP address).  Currently only ip is supported for family.

       nlength		   On input, the maximum length, in bytes, of the name to be returned.	(error if less than  size  of  "nnnnn.nnnn").	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.

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