/* The socket-oriented system calls are handled unusually 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.
|
||
