socketcall - socket system calls
int socketcall(int call, unsigned long *args);
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().
This call is specific to Linux, and should not be used in programs
intended to be portable.
On a few architectures, for example ia64, there is no socketcall()
system call; instead socket(2), accept(2), bind(2), and so on really
are implemented as separate system calls.
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), shutdown(2), socket(2),
