NAME
     getrtable,	setrtable -- get and set the default routing table of the cur-
     rent process

     #include <sys/socket.h>

     int
     getrtable(void);

     int
     setrtable(int rtableid);

DESCRIPTION
     getrtable() and setrtable() manipulate the	routing	table and routing do-
     main associated with the current process.

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

RETURN VALUES
     getrtable() returns the routing table of the current process.  Upon suc-
     cessful completion, setrtable() returns 0 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 table of
			the calling process is already set to a	non-zero
			value.
