gensio_to_sergensio.3(3)

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.
