Hi,
As per the source code(
https://gitlab.denx.de/Xenomai/xenomai/-/blob/v3.0.9/kernel/drivers/net/stack/ipv4/tcp/tcp.c),
I could see that some code have relation to _RTIOC_LISTEN.For details, see
below.
*/*** * rt_tcp_ioctl */static int rt_tcp_ioctl(struct rtdm_fd *fd,
unsigned int request, void __user *arg){ ... case _RTIOC_LISTEN: val =
rtnet_get_arg(fd, &_val, arg, sizeof(long)); if (IS_ERR(val)) return
PTR_ERR(val); return rt_tcp_listen(ts, *val); case ...}*
There is also some code about *_RTIOC_LISTEN in the drivers of IDDP
and XDDP.*You could see it in the url(
https://gitlab.denx.de/Xenomai/xenomai/-/blob/v3.0.9/kernel/drivers/ipc/xddp.c).For
details, see below.
*static int __xddp_ioctl(struct rtdm_fd *fd, unsigned int request, void
*arg){ ... case _RTIOC_LISTEN: COMPAT_CASE(_RTIOC_ACCEPT): ret =
-EOPNOTSUPP; break; ...}*
*Does these _RTIOC_LISTEN showed above in the two source code files
have some relations？* I don't think so.
* There really exist some api relation to XDDP and IDDP.*For instance,
socket, bind, connect,etc.
*And when you transport your messages through tcp or udp, you also use
the apis with the same name.*
* So, i am a little confused.*
Thank you for your attention.
Look forward to hearing from you.
