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

NAME         top

       socketcall - socket system calls

SYNOPSIS         top

       int socketcall(int call, unsigned long *args);

DESCRIPTION         top

       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         top

       This call is specific to Linux, and should not be used in programs
       intended to be portable.

NOTES         top

       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.
