/* 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. */
