# ServerHelperApi::Exists(ClientUser*,Error*)

Checks for the existence of a personal server.

Virtual? | No |
Class | `ServerHelperApi` |
Arguments | `ClientUser * ui` | A `ClientUser` object
Returns | `int` | returns 1 if a personal server exists in the root dir

## Notes

Many `ServerHelperApi` methods expect there to be no existing server in the path set by `SetDvcsDir()`. `Exists()` is useful for avoiding potential errors caused by pre-existing servers.

## Example

    // Check that we don't already have a DVCS tree at the target directory
    personalServer.SetDvcsDir( "/User/home/dev", &e );
    if( e.Test() )
        return 1;

    if( personalServer.Exists( &ui, &e ) )
        return 1;
