/* 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.
