## Detailed Description

Specialization of `Connection` for Windows named pipes.

This class just simplifies the connection creation interface of `Connection`. It does not add new functionality.

## Constructor & Destructor Documentation

mysqlpp::WindowsNamedPipeConnection::WindowsNamedPipeConnection | ( | const char * | db,
|  | const char * | user = `0`,
|  | const char * | password = `0`
| ) |  |
| inline

Create object and connect to database server over Windows named pipes in one step.

Parameters

  db | name of database to use
  user | user name to log in under, or 0 to use the user name the program is running under
  password | password to use when logging in

mysqlpp::WindowsNamedPipeConnection::WindowsNamedPipeConnection | ( | const WindowsNamedPipeConnection & | other | ) |
| inline

Establish a new connection using the same parameters as an existing connection.

Parameters

  other | pre-existing connection to clone

## Member Function Documentation

bool mysqlpp::WindowsNamedPipeConnection::connect | ( | const char * | db = `0`,
|  | const char * | user = `0`,
|  | const char * | password = `0`
| ) |  |

Connect to database after object is created.

It's better to use the connect-on-create constructor if you can. See its documentation for the meaning of these parameters.

If you call this method on an object that is already connected to a database server, the previous connection is dropped and a new connection is established.

bool mysqlpp::WindowsNamedPipeConnection::is_wnp | ( | const char * | server | ) |
| static

Check that given string denotes a Windows named pipe connection to MySQL.

Parameters

  server | the server address

Returns
  false if server address does not denote a Windows named pipe connection, or we are not running on Windows
