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  porta‐
       ble.

NOTES
       On  a some architectures—for example, x86-64 and ARM—there is no socketcall() system call;
       instead socket(2), accept(2), bind(2), and so on really are implemented as separate system
       calls.

SEE ALSO
       accept(2),  bind(2), connect(2), getpeername(2), getsockname(2), getsockopt(2), listen(2),
       recv(2), recvfrom(2), recvmsg(2), send(2),  sendmsg(2),  sendto(2),  setsockopt(2),  shut‐
       down(2), socket(2), socketpair(2)
