Detailed Description
The unixsocketserver class allows you to write programs that can talk to other programs on the same machine over TCP stream sockets.
Inet sockets (see the inetsocketserver class) can be used by clients and servers on the same machine as well, but Unix sockets generally perform better.
Some platforms (line Windows) don't support Unix sockets. For those platforms, Unix sockets are simulated using Inet sockets on localhost by translating the socket filename to a port. See unixsocketutil::filenameToPort() for details.
The unixsocketserver class provides methods for setting up sockets and accepting client connections. Its ultimate parent class: transport, provides methods for reading and writing data and closing connections. An immediate parent class: unixsocket provides methods for passing file descriptors between connected instances of unixservertsocket's and unixsocketclient's.
If you need to listen on more than 1 socket at a time, you should use the unixsocketserver class (and possibly the unixsocketserver class) in conjunction with the listener class.
Constructor & Destructor Documentation
◆ unixsocketserver()
| unixsocketserver::unixsocketserver | ( | ) |
Creates an instance of the unixsocketserver class.
◆ ~unixsocketserver()
|
virtual |
Deletes this instance of the unixsocketserver class.
Member Function Documentation
◆ accept()
|
virtual |
Removes the client connection from the queue and associates a new socket with that connection. Communication with the client may be done over this new socket.
Returns an unixsocketclient on success and NULL on failure.
Reimplemented from server.
◆ bind()
|
virtual |
Associates the socket with a file and sets permissions on that file.
Returns true on success and false on failure.
Reimplemented from server.
◆ close()
|
virtual |
Closes the socket. Returns true on success and false on failure.
Reimplemented from filedescriptor.
◆ getMask()
| mode_t unixsocketserver::getMask | ( | ) |
Returns the umask that will be used when associating the socket with a file.
◆ listen() [1/2]
|
virtual |
Waits until a client connects then places that connection in queue. Up to "backlog" connections may be queued before future conenctions are refused.
Returns true on success and false on failure.
Reimplemented from server.
◆ listen() [2/2]
| bool unixsocketserver::listen | ( | const char * | filename, |
| mode_t | mask, | ||
| uint32_t | backlog | ||
| ) |
Convenience method that calls open(), bind() and listen(). If you need to set socket options or do anything else special between those discrete steps then you should use the methods individually.
Listen on "filename" and allow "backlog" connections to pile up before refusing them. Set the permissions on "filename" using umask "mask".
Returns true on success and false on failure.
◆ open()
| bool unixsocketserver::open | ( | ) |
Creates the actual socket and initializes the instance to use "filename" when bind() is called. The permissions on "filename" will be set using umask "mask".
Returns true on success and false on failure.
◆ setMask()
| void unixsocketserver::setMask | ( | mode_t | mask | ) |
Sets the umask that will be used when associating the socket with a file.
