Wait until the Unix domain socket is bound

Question

I am writing a client application that connects to a server process through a Unix domain socket. If the server process is not running, I want the client to wait until the server starts and listens for connections on the socket.

I currently have a retry loop in the client that calls connect () every second until it is successfully connected to the socket.

Is there any function that I can call that will simply block until a specific named socket is created (for example, "/ var / mysock") and is not bound to the server process?
