Functions

func CheckAvailability

func CheckAvailability(port int) bool

func GetFreePort

func GetFreePort(defaultPort int) (int, error)

GetFreePort returns a free port number. If the default port is not available, it will try to find a free port, checking at most the next 1024 ports. If no free port is found, it will get a random free port. If that fails, it will return the default port. If the default port is set to 0, 8080 will be used instead.
