Detailed Description

The unixsocketclient class allows you to write programs that can talk to other programs on the same machine over TCP stream sockets.

Inet sockets (see the inetsocketclient 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 unixsocketclient class provides methods for connecting to servers. Its ultimate parent class: filedescriptor provides methods for reading and writing data and closing connections.

Constructor & Destructor Documentation

◆ unixsocketclient() [1/2]

unixsocketclient::unixsocketclient ( )

Creates an instance of the unixsocketclient class.

◆ unixsocketclient() [2/2]

unixsocketclient::unixsocketclient ( const unixsocketclient u)

Creates an instance of the unixsocketclient class. that is a copy of "u".

◆ ~unixsocketclient()

virtual unixsocketclient::~unixsocketclient ( )
virtual

Deletes this instance of unixsocketclient.

Member Function Documentation

◆ close()

bool unixsocketclient::close ( )
virtual

Closes the socket. Returns true on success and false on failure.

Reimplemented from filedescriptor.

◆ connect()

int32_t unixsocketclient::connect ( )
virtual

Attempts to connect to the "filename" set earlier. If the connection fails, it will retry, for a total of "tries" attempts, waiting "retrywait" seconds between each attempt.

Setting "tries" to 0 will cause it to try to connect indefinitely. Setting "retrywait" to 0 will cause it to try to connect over and over as fast as possible (not recommended).

Each attempt to connect will wait "timeoutsec" seconds and "timeoutusec" microseconds for the connect to succeed. Specifying -1 for either parameter will cause the attempt to wait until the underlying protocol times out which may be up to 2 minutes.

Returns RESULT_SUCCESS on success and RESULT_ERROR on failure.

Reimplemented from client.

◆ initialize() [1/2]

void unixsocketclient::initialize ( constnamevaluepairs *  cd)
virtual

Queries namevaluepairs "cd" for "filename", "timeoutsec", "timeoutusec", "retrywait" and "tries". Initializes the class to use the result when connect() is called.

Reimplemented from client.

◆ initialize() [2/2]

void unixsocketclient::initialize ( const char *  filename,
int32_t  timeoutsec,
int32_t  timeoutusec,
uint32_t  retrywait,
uint32_t  tries 
)

Initializes the class to use "filename", "timeoutsec", "timeoutusec", "retrywait" and "tries" when connect() is called.

◆ operator=()

unixsocketclient& unixsocketclient::operator= ( const unixsocketclient u)

Makes this instance of the unixsocketclient class identical to "u".
