Functions

func MustTake

func MustTake(n int) (ports []int)

MustTake is the same as Take except it panics on error.

func Return

func Return(ports []int)

Return returns a block of ports back to the general pool. These ports should have been returned from a call to Take().

func Take

func Take(n int) (ports []int, err error)

Take returns a list of free ports from the allocated port block. It is safe to call this method concurrently. Ports have been tested to be available on 127.0.0.1 TCP but there is no guarantee that they will remain free in the future.
