Socket Programming socket
Hello,
I actually try to make client-server program.
I'm using SCO OpenServer Release 5.0.0 and when I try to compile my code (by TELNET) I've got this error :
Quote:
Undefined first referenced
symbol in file
socket /usr/tmp/cca000Hf1.o
a.out: fatal error: Symbol referencing errors. No output written to a.out
I'm just using this simple code :
Quote:
#include <sys/types.h>
#include <sys/socket.h>
#include <sys/un.h>
#include <stdio.h>
#define ADDRESS "192.168.0.191"
char *strs[3] = {"Message test - Socket"};
main()
{
char c;
FILE *fp;
int fromlen;
register int i, s, ns, len;
struct sockaddr_un saun, fsaun;
if ((s = socket(AF_UNIX, SOCK_STREAM, 0)) < 0)
{
perror("server: socket");
exit(1);
}
exit(0);
}
and I get the same error if I use :
Quote:
gcc serv.c
or
cc serv.c
or
c++ serv.c
If someone can help me,
Thanks

coro::socket
Socket(3pm) User Contributed Perl Documentation Socket(3pm)
NAME
Coro::Socket - non-blocking socket-I/O
SYNOPSIS
use Coro::Socket;
# listen on an ipv4 socket
my $socket = new Coro::Socket PeerHost => "localhost",
PeerPort => 'finger';
# listen on any other type of socket
my $socket = Coro::Socket->new_from_fh
(IO::Socket::UNIX->new
Local => "/tmp/socket",
Type => SOCK_STREAM,
);
DESCRIPTION
This module is an AnyEvent user, you need to make sure that you use and run a supported event loop.
This module implements socket-handles in a coroutine-compatible way, that is, other coroutines can run while reads or writes block on the
handle. See Coro::Handle, especially the note about prefering method calls.
IPV6 WARNING
This module was written to imitate the IO::Socket::INET API, and derive from it. Since IO::Socket::INET does not support IPv6, this module
does neither.
Therefore it is not recommended to use Coro::Socket in new code. Instead, use AnyEvent::Socket and Coro::Handle, e.g.:
use Coro;
use Coro::Handle;
use AnyEvent::Socket;
# use tcp_connect from AnyEvent::Socket
# and call Coro::Handle::unblock on it.
tcp_connect "www.google.com", 80, Coro::rouse_cb;
my $fh = unblock +(Coro::rouse_wait)[0];
# now we have a perfectly thread-safe socket handle in $fh
print $fh "GET / HTTP/1.0 15 12 15 12";
local $/;
print <$fh>;
Using "AnyEvent::Socket::tcp_connect" gives you transparent IPv6, multi-homing, SRV-record etc. support.
For listening sockets, use "AnyEvent::Socket::tcp_server".
$fh = new Coro::Socket param => value, ...
Create a new non-blocking tcp handle and connect to the given host and port. The parameter names and values are mostly the same as for
IO::Socket::INET (as ugly as I think they are).
The parameters officially supported currently are: "ReuseAddr", "LocalPort", "LocalHost", "PeerPort", "PeerHost", "Listen", "Timeout",
"SO_RCVBUF", "SO_SNDBUF".
$fh = new Coro::Socket PeerHost => "localhost", PeerPort => 'finger';
