Function NewFileServer

drive/driveimpl/fileserver.go:42–62

NewFileServer constructs a FileServer. The server attempts to listen at a random address on 127.0.0.1. The listen address is available via the Addr() method. The server has to be told about shares before it can serve them. This is accomplished either by calling SetShares(), or locking the shares w

// called.
