SOCKETCALL(2)              Linux Programmer's Manual             SOCKETCALL(2)

NAME
       socketcall - socket system calls
SYNOPSIS
       int socketcall(int call, unsigned long *args);
DESCRIPTION
       socketcall()  is  a  common  kernel  entry  point for the socket system
       calls.  call determines which socket function to invoke.   args  points
       to a block containing the actual arguments, which are passed through to
       the appropriate call.
       User programs should call the  appropriate  functions  by  their  usual
       names.   Only  standard library implementors and kernel hackers need to
       know about socketcall().
CONFORMING TO
       This call is specific to Linux, and should  not  be  used  in  programs
       intended to be portable.
NOTES
       On a some architectures--for example, x86-64 and ARM--there is no sock-
       etcall() system call; instead socket(2), accept(2), bind(2), and so  on
       really are implemented as separate system calls.
