Variables
const ssize_t	FB_TRANSPORT_CLOSED = 0
	Connection closed normally. Returned by read transport function only.
const ssize_t	FB_TRANSPORT_INCOMPLETE = -1
	An action was incomplete, but can be retried in the future.
const ssize_t	FB_TRANSPORT_FAILURE = -2
	An action failed permanently; the connection has failed and should be closed.
const FB_TRANSPORT_FUNCS	fb_transport_unencrypted
	Transport virtual method table for unenrypted connections.
const FB_TRANSPORT_FUNCS	fb_transport_read_file
	Transport virtual method table for reading from files.
