# ClientApi::Init( Error * )

Establish a connection and prepare to run commands.

Virtual? | No |
Class | `ClientApi` |
Arguments | `Error *e` | an `Error` object
Returns | `void` |

## Notes

`Init()` must be called to establish a connection before any commands can be sent to the server. Each call to `Init()` must be followed by exactly one call to `Final()`.

If an error occurs during `Init()`, it is most likely a connection error, with a severity of `E_FATAL`.

## Example

The following code from `p4api.cc` opens a connection with `Init()`, sets arguments, runs a command, and closes the connection with `Final()`.

    ClientUser ui;
    ClientApi client;
    Error e;

    client.Init( &e );

    client.SetArgv( argc - 2, argv + 2 );
    client.Run( argv[1], &ui );
    client.Final( &e );
    return 0;
