## Detailed Description

The socketserver class provides a base class for classes that implement the server side of a client-server communication model over a socket.

## Constructor & Destructor Documentation

socketserver::socketserver | ( |  | ) |

Creates an instance of the socketserver class.

socketserver::socketserver | ( | const socketserver & | s | ) |

Creates an instance of the socketserver class that is a copy of "s".

virtual socketserver::~socketserver | ( |  | ) |
| virtual

Deletes this instance of the socketserver class.

## Member Function Documentation

bool socketserver::dontLingerOnClose | ( |  | ) |

Instructs the socket to close immediately when close() is called, dumping any data that may still be buffered but that it may not have received. This is the default.

Returns true on success and false on failure.

bool socketserver::dontReuseAddresses | ( |  | ) |

Prevents sockets in the TIME_WAIT state from being reused. This is the default.

Returns true on success and false on failure.

virtual int32_t socketserver::ioCtl | ( | int32_t | command,
|  | void * | arg
| ) |  | const
| virtual

Use the ioctl() system call to perform various low-level file descriptor operations.

Reimplemented from filedescriptor.

virtual bool socketserver::isUsingNonBlockingMode | ( |  | ) | const
| virtual

Returns true if the file descriptor is in non-blocking mode and false otherwise.

Reimplemented from filedescriptor.

bool socketserver::lingerOnClose | ( | int32_t | timeout | ) |

Instructs the socket to stay open for "timeout" seconds even after close() is called to allow it to receive any data that may still be buffered. The default is not to linger on close.

Returns true on success and false on failure.

virtual bool socketserver::listen | ( | int32_t | backlog | ) |
| 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.

Reimplemented in unixsocketserver, and inetsocketserver.

socketserver& socketserver::operator= | ( | const socketserver & | s | ) |

Makes this instance of the socketserver class identical to "s".

bool socketserver::reuseAddresses | ( |  | ) |

Allows sockets in the TIME_WAIT state to be reused. The default is to allocate a new socket.

Returns true on success and false on failure.

virtual bool socketserver::supportsBlockingNonBlockingModes | ( |  | ) |
| virtual

Returns false if the system doesn't support blocking/nonblocking modes and true otherwise.

Reimplemented from filedescriptor.

virtual bool socketserver::useBlockingMode | ( |  | ) | const
| virtual

Puts the file descriptor in blocking mode. Returns true on success and false on failure. Returns false if the system doesn't support blocking/nonblocking modes.

Reimplemented from filedescriptor.

virtual bool socketserver::useNonBlockingMode | ( |  | ) | const
| virtual

Puts the file descriptor in non-blocking mode. Returns true on success and false on failure. Returns false if the system doesn't support blocking/nonblocking modes.

Reimplemented from filedescriptor.
