int 
DbChannel::close(u_int32_t flags);

The DbChannel::close() method closes the DbChannel handle, freeing any resources allocated to the handle. All DbChannel handles must be closed before the encompassing environment handle is closed. Also, all on-going messaging operations on the channel should be allowed to complete before attempting to close the channel handle.

After DbChannel::close() has been called, regardless of its return, the DbChannel handle may not be accessed again.

The DbChannel::close() method either returns a non-zero error value or throws an exception that encapsulates a non-zero error value on failure, and returns 0 on success.
