+   They are all gated through the single `socketcall' system call number.
+   `socketcall' takes two arguments: the first is the subcode, specifying
+   which socket function is being called; and the second is a pointer to
+   the arguments to the specific function.
+
+   The .S files for the other calls just #define socket and #include this.  */
