34 /* The socket-oriented system calls are handled unusually in Linux.
35 They are all gated through the single `socketcall' system call number.
36 `socketcall' takes two arguments: the first is the subcode, specifying
37 which socket function is being called; and the second is a pointer to
38 the arguments to the specific function.
40 The .S files for the other calls just #define socket and #include this. */
