SYNOPSIS

14
15       struct gensio *sergensio_to_gensio(struct sergensio *serio);

DESCRIPTION

22       gensio_to_sergensio  return  the sergensio object for a gensio.  It re‐
23       turns NULL if there is no sergensio for the gensio.  Note that this may
24       be  a  sergensio  object  for  a child of the passed in gensio.  If the
25       passed in gensio is not a sergensio, it will search through  the  chil‐
26       dren for a gensio that is also a sergensio.  This way, say, if you have
27       an conacc gensio running over a serialdev, and you  receive  an  serial
28       event,  you  can just call gensio_to_sergensio for the passed in object
29       and it will give you the sergensio you should  be  working  with.   The
30       first  time this is called on a gensio it associates the sergensio with
31       the passed in gensio.
32
33       sergensio_to_gensio returns the gensio for a given sergensio.  It  can‐
34       not  fail.   Note  that  this  returns  the  gensio  passed  in to gen‐
35       sio_to_sergensio not the gensio directly associated with the passed  in
36       sergensio.
37
38       sergensio_get_user_data returns the gensio user data for the associated
39       gensio.
40
41       sergensio_is_client returns true if the sergensio a client or false  if
42       it is a server.
