+.Fa fib .
+The
+.Fa fib
+argument
+may be between 0 and the current system maximum which 
+may be retrieved by the 
+.Em net.fibs
+sysctl.
+The default fib of the process will be applied to all protocol families 
+that support multiple fibs, and ignored by those that do not.
+The default fib for a process may be overidden for a socket with the use
+of the SO_SETFIB socket option.
+.Sh RETURN VALUES
+.Rv -std setfib
+.Sh ERRORS
+The
+.Fn kill
+system call
+will fail and no action will be taken and return
