L191[22:57:57] <Hawk777> Hm… device_open
in tty.c should probably be “int device_open(void) { …” rather than
“int device_open() { …”, but that doesn’t explain the segfault,
that’s just a kind of tidiness thing.
L192[22:58:06] <Hawk777> Is “test”
printed?
L193[22:59:01] <Hawk777> “*(void **)
(&device_open) = dlsym(dlfd, "device_open");” is also
a slightly odd-looking construct to me, I would personally write it
“device_open = (int (*)(void)) dlsym(dlfd,
"device_open");” but again I don’t think that explains
the segfault.

works fine.

major differently?
<Ocawesome101> hm. am i doing anything
major differently?L254[23:19:18] <Hawk777> Well, a couple of
differences. I use RTLD_GLOBAL|RTLD_LAZY, you use
RTLD_LOCAL|RTLD_NOW. Not sure whether that matters. I also look up
the address of a variable, not a function (the variable is a
structure which contains function pointers, but I don’t dlsym
actual functions directly).
L255[23:19:31] <Hawk777> I also pass
RTLD_DEFAULT rather than a specific handle to dlsym.
L256[23:19:37] <Hawk777> But none of these
seem like they should break things so badly.
L257[23:19:57] <Ocawesome101> i agree

L261[23:23:14] <Hawk777> Is tty.so linked
to any other libraries that are *not* also linked by the main
executable? I *think* RTLD_LOCAL would mean it gets its own copy of
any such libraries.
L262[23:23:17] <Hawk777> Which might be
weird.
L263[23:23:35] <Ocawesome101> i don't believe so

<Ocawesome101> thanksL280[23:31:33] <Hawk777> TBH probably
better to just not even try to dlclose ever, unloading dynamically
linked stuff is kinda… messy.
L281[23:34:27] <Amanda> It's pretty much a
no-op isn't it?
L282[23:34:44] <Amanda> since there's no
real way to know if you've got a pointer there still?
L283[23:36:54] <Hawk777> Well, it *could*
do nothing if someone else still has a reference to the library
open. If the refcount reaches zero it will unload (as Oca just
found out the hard way), just as you say, there could be pointers
still pointing into the area, so it’s very hard to be certain it’s
safe to do so.
