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.
