26 They are all gated through the single `socketcall' system call number.
27 `socketcall' takes two arguments: the first is the subcode, specifying
28 which socket function is being called; and the second is a pointer to
29 the arguments to the specific function.
31 The .S files for the other calls just #define socket and #include this.
32 They also #define a 'number-of-arguments' word in NARGS, which
