NAME

       gensio_acc_control - Perform gensio accepter specific actions

SYNOPSIS

       #include <gensio/gensio.h>

       int gensio_acc_control(struct gensio_accepter *acc, int depth,
                           bool get, unsigned int option,
                           char *data, gensiods *datalen);

DESCRIPTION

       gensio_acc_control  performs  a gensio accepter specific operation on the gensio accepter.
       This works exactly like gensio_control(3), see that for details on get, depth, and how the
       data and datalen work.

       gensio  control  operations  in  option  depend  on the particular gensio.  Below some are
       documented, but there may be other controls available.  See the  gensio  documentation  in
       gensio(5) for details.

   GENSIO_ACC_CONTROL_LADDR
       Return  the given local address for the given gensio.  Since a single gensio may have more
       than one local address, this control provides a means to tell which one.  The data  string
       passed  in  should  be  the  string  representation  of  a  the  number (like created with
       snprintf()) for the particular index you want to fetch.  If you specify  a  number  larger
       than  the  number  of  open listen sockets, GE_NOTFOUND is returned.  The return data is a
       string holding the address.

       Note that a single fetched string may contain  more  than  one  address.   These  will  be
       separated by semicolons.  In some cases addresses may change dynamically (like with SCTP),
       so you get a single set of addresses.

   GENSIO_ACC_CONTROL_LPORT
       Return the port for the given local address for the given gensio.  Since a  single  gensio
       may  have  more  than  one local address, this control provides a means to tell which one.
       The data string passed in should be the  string  representation  of  a  the  number  (like
       created  with  snprintf())  for  the particular index you want to fetch.  If you specify a
       number larger than the number of open listen sockets, GE_NOTFOUND is returned.  The return
       data is a string holding the port number.

   GENSIO_ACC_CONTROL_TCPDNAME
       Get or set the TCPD name for the gensio, only for TCP gensios.

RETURN VALUES

       Zero is returned on success, or a gensio error on failure.
