NAME
     getrtable, setrtable - get and set the default routing domain of the
     current process

SYNOPSIS
     #include <sys/types.h>
     #include <sys/socket.h>

     int
     getrtable(void);

     int
     setrtable(int rtableid);

DESCRIPTION
     getrtable() and setrtable() manipulate the routing table and routing
     domain associated with the current process.

     Only the superuser is allowed to change the process routing domain if it
     is already set to a non-zero value.

RETURN VALUES
     A 0 is returned if the call succeeds, -1 if it fails.

ERRORS
     The call succeeds unless:

     [EINVAL]	   The value of the rtableid argument is not a valid routing
		   table.

     [EPERM]	   The user is not the superuser and the routing domain of the
		   calling process is already set to a non-zero value.
