/* 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. */
