## Detailed Description

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

## Constructor & Destructor Documentation

## ◆ client() [1/2]

client::client | ( |  | ) |

Creates an instance of the client class.

## ◆ client() [2/2]

client::client | ( | const client & | c | ) |

Creates an instance of the client class that is a copy of "c".

## ◆ ~client()

virtual client::~client | ( |  | ) |
| virtual

Deletes this instance of the client class.

## Member Function Documentation

## ◆ connect()

virtual int32_t client::connect | ( |  | ) |
| virtual

This method may be implemnted by a child class to open a connection to a server, presumably specified in the "cd" parameter of the initalize() method.

This method return an int32_t instead of a bool so child classes that have non atomic connection procedures (such as a modem) can implement return codes other than success or failure (such as abort).

This implementation just returns RESULT_SUCCESS.

Reimplemented in unixsocketclient, modemclient, and inetsocketclient.

## ◆ getVerboseConnectError()

virtual const char* client::getVerboseConnectError | ( |  | ) |
| virtual

This method returns NULL by default but may be implemented by a child class to return a detailed reason for a connect failure.

## ◆ initialize()

virtual void client::initialize | ( | constnamevaluepairs * | cd | ) |
| virtual

This method may be implemented by a child class to initialize this instance with the parameters defined in "cd".

This implementation does nothing.

Reimplemented in unixsocketclient, modemclient, and inetsocketclient.

## ◆ operator=()

client& client::operator= | ( | const client & | c | ) |

Makes this instance of the client class identical to "c".

## ◆ setVerboseConnectError()

virtual void client::setVerboseConnectError | ( | const char * | error | ) |
| virtual

This method may be used to set the verbose connect error.
