 .Sh DESCRIPTION
 The
 .Fn socketpair
 call creates an unnamed pair of connected sockets in
 the specified domain
-.Fa d ,
+.Fa domain ,
 of the specified
 .Fa type ,
 and using the optionally specified
 .Fa protocol .
 The descriptors used in referencing the new sockets
 are returned in
-.Fa sv Ns [0]
+.Fa socket_vector Ns [0]
 and
-.Fa sv Ns [1] .
+.Fa socket_vector Ns [1] .
 The two sockets are indistinguishable.
-.Sh DIAGNOSTICS
-A 0 is returned if the call succeeds, -1 if it fails.
+.Sh RETURN VALUES
