Hello Guys,
I can't find useful information on sosend(), I would like to send some
plain text through sosend()
Here is what i got so far, I don't know how to use mbuf with sosend()
to achieve this.
ret = socreate(PF_INET, &s, SOCK_STREAM, IPPROTO_TCP,
curthread->td_ucred, curthread);

You need to stick your "plain text" in an mbuf. See 'man 9 socket' and

Hello, freebsd-hackers

there is a which is included in a lot of headers, but a
few of them instead of including it, generate "#error this file needs

seems like an omission, but if it's intentional I'm curious why it is
so.
thanks a lot,

No my code doesn't work, I thought it may be because that soaccept()
-which is not found in man 9- is non-blocking, so i've to put my code
in a thread.
Now i got another problem, when I open a text file from this thread,
the kernel crashes, I'm sure that its the thread.

If the kernel crashed, I assume you have a dump and a backtrace and can
tell us *where* it crashed?

This is wrong, and contradicts what I wrote further down. Just ignore
it.
