CentOS 7.0 - man page for socketcall (centos section 2)

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 func- tion 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 socketcall() system call; instead socket(2), accept(2), bind(2), and so on really are implemented as separate system calls.
