NAME
       gensio_to_sergensio, sergensio_to_gensio, sergensio_get_user_data,
       sergensio_is_client - General information and conversion routines for a
       sergensio

SYNOPSIS
       #include <gensio/sergensio.h>

       struct sergensio *gensio_to_sergensio(struct gensio *io);

       struct gensio *sergensio_to_gensio(struct sergensio *serio);

       void *sergensio_get_user_data(struct sergensio *serio);

       bool sergensio_is_client(struct sergensio *serio);

DESCRIPTION
       gensio_to_sergensio return the sergensio object for a gensio.  It
       returns NULL if there is no sergensio for the gensio.  Note that this
       may be a sergensio object for a child of the passed in gensio.  If the
       passed in gensio is not a sergensio, it will search through the
       children for a gensio that is also a sergensio.  This way, say, if you
       have an conacc gensio running over a serialdev, and you receive an
       serial event, you can just call gensio_to_sergensio for the passed in
       object and it will give you the sergensio you should be working with.
       The first time this is called on a gensio it associates the sergensio
       with the passed in gensio.

       sergensio_to_gensio returns the gensio for a given sergensio.  It
       cannot fail.  Note that this returns the gensio passed in to
       gensio_to_sergensio not the gensio directly associated with the passed
       in sergensio.

       sergensio_get_user_data returns the gensio user data for the associated
       gensio.

       sergensio_is_client returns true if the sergensio a client or false if
       it is a server.
