SOCKET dupSocket (SOCKET s, Socket::State state)

The Socket is used as the base for all Internet protocol services under Common C++.

A socket is a system resource (or winsock descriptor) that occupies a specific port address (and may be bound to a specific network interface) on the local machine. The socket may also be directly connected to a specific socket on a remote internet host.

This base class is not directly used, but is provided to offer properties common to other Common C++ socket classes, including the socket exception model and the ability to set socket properties such as QoS, 'sockopts' properties like Dont-Route and Keep-Alive, etc.

Author:

David Sugar [email protected] base class of all sockets.

ost::Socket::Socket (intdomain, inttype, intprotocol = \fC0\fP)\fC [protected]\fP

An unconnected socket may be created directly on the local machine. Sockets can occupy both the internet domain (AF_INET) and UNIX socket domain (AF_UNIX) under unix. The socket type (SOCK_STREAM, SOCK_DGRAM) and protocol may also be specified. If the socket cannot be created, an exception is thrown.

Parameters:

domain socket domain to use.

type base type and protocol family of the socket.

protocol specific protocol to apply.

ost::Socket::Socket (\fBSOCKET\fPfd)\fC [protected]\fP

A socket object may be created from a file descriptor when that descriptor was created either through a socket() or accept() call. This constructor is mostly for internal use.

Parameters:

fd file descriptor of an already existing socket.

ost::Socket::Socket ()\fC [protected]\fP

Create an inactive socket object for base constructors.

ost::Socket::Socket (const \fBSocket\fP &source)\fC [protected]\fP

A socket can also be constructed from an already existing Socket object. On POSIX systems, the socket file descriptor is dup()'d. On Win32, DuplicateHandle() is used.

Parameters:

source of existing socket to clone.

virtual ost::Socket::~Socket ()\fC [virtual]\fP

The socket base class may be 'thrown' as a result of an error, and the 'catcher' may then choose to destroy the object. By assuring the socket base class is a virtual destructor, we can assure the full object is properly terminated.

\fBError\fP ost::Socket::bufferSize (unsignedsize)\fC [protected]\fP

Set the total protocol stack network kernel buffer size for both send and receive together.

Returns:

errSuccess on success

Parameters:

size of buffer.

\fBError\fP ost::Socket::error (\fBError\fPerror, const char *err = \fCNULL\fP, longsystemError = \fC0\fP) const\fC [protected]\fP

This service is used to throw all socket errors which usually occur during the socket constructor.

Parameters:

error defined socket error id.

err string or message to pass.

systemError the system error# that caused the error

void ost::Socket::error (const char *err) const\fC [inline]\fP, \fC [protected]\fP

This service is used to throw application defined socket errors where the application specific error code is a string.

Parameters:

err string or message to pass.

References ost::error().

\fBError\fP ost::Socket::getErrorNumber (void) const\fC [inline]\fP

Often used by a 'catch' to fetch the last error of a thrown socket.

Returns:

error number of Error error.

Examples: tcpthread.cpp.

const char* ost::Socket::getErrorString (void) const\fC [inline]\fP

Often used by a 'catch' to fetch the user set error string of a thrown socket, but only if EXTENDED error codes are used.

Returns:

string for error message.

\fBIPV4Host\fP ost::Socket::getIPV4Local (\fBtpport_t\fP *port = \fCNULL\fP) const

Get the local address and port number this socket is currently bound to.

Parameters:

port ptr to port number on local host.

Returns:

host address of interface this socket is bound to.

Referenced by ost::TCPSocket::getLocal().

\fBIPV4Host\fP ost::Socket::getIPV4NAT (\fBtpport_t\fP *port = \fCNULL\fP) const

Perform NAT table lookup for this socket. Used to allow an application to know the original ip:port pair the the client 'thinks' it is connecting to. Used mostly to transparently impersonate a remote server/service.

On error, 0.0.0.0:0 is returned and one of the following error codes is set: errServiceUnavailable - if nat is not supported on the current platform or if it was not compiled; errLookupFail - if the nat syscall failed for some reason (extended error code); errSearchErr - if the socket does not have nat information (i.e. is not nated).

NAT lookup is supported on NetFilter for ipv4 and ipv6 (Linux), IPFilter for ipv4 (Solaris, *BSD except OpenBSD, HP-UX, etc.) and Packet Filter for ipv4 and ipv6 (OpenBSD). When using IPFilter or Packet Filter, the first NAT lookup must be performed as root (the NAT device is read only for root and is opened once, unless an error occurs). Permissions on the nat device may be changed to solve this.

Warning:

When using IPFilter and Packet Filter, application data model must be the same as the running kernel (32/64 bits).

Parameters:

port ptr to NATed port number on local host.

Returns:

NATed host address that this socket is related to.

\fBIPV4Host\fP ost::Socket::getIPV4Peer (\fBtpport_t\fP *port = \fCNULL\fP) const

Get the host address and port of the socket this socket is connected to. If the socket is currently not in a connected state, then a host address of 0.0.0.0 is returned.

Parameters:

port ptr to port number of remote socket.

Returns:

host address of remote socket.

virtual \fBIPV4Host\fP ost::Socket::getIPV4Sender (\fBtpport_t\fP *port = \fCNULL\fP) const\fC [virtual]\fP

May be used to examine the origin of data waiting in the socket receive queue. This can tell a TCP server where pending 'connect' requests are coming from, or a UDP socket where it's next packet arrived from.

Parameters:

port ptr to port number of sender.

Returns:

host address, test with 'isInetAddress()'.
