public static SelectableChannel readWriteSelectableChannel(FileDescriptor fd, Channels.SelectableChannelCloser closer)

Creates a selectable channel to a file descriptor that supports an operation-set of OP_READ and OP_WRITE. The selectable channel will be created by the default SelectorProvider.

The given file descriptor is a socket or resource that can be multiplexed by a Selector for read and write readiness. Great care is required to coordinate direct use of the file descriptor with the use of the selectable channel. In particular, changing the blocking mode or closing the file descriptor without careful coordination will result in unspecified and unsafe side effects. The given SelectableChannelCloser is invoked to close the file descriptor and to coordinate the closing when the channel is registered with a Selector.

If there is a security manager set then its checkRead and checkWrite methods are invoked to check that the caller has permission to both read from and write to the file descriptor.
