+/* The socket-oriented system calls are handled unusally in Linux.
+ 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.
+ They also #define a 'number-of-arguments' word in NARGS, which
+ defaults to 3. */
