I've been working on expanding a serverplugin that'll load other
directories as content directories. (If you've played Garrysmod then I'm
trying to recreate an addon system.)
I've gotten the interfaces sorted out but I keep hitting this notorious
(to me at least) exception 'Privileged instruction'. Currently I'm
trying to mount folders in this structure:
<steam username>\half-life 2 episode two\Addons\<actual folders to mount>
My (relevant) code:
void MountAddon(const char *AddonPath)
{
filesystem->AddSearchPath(AddonPath, "GAME"); // I'm assuming that
"GAME" refers to the directory where the hl2.exe file is located
}
I've called it with this test addon/code (the directory exists):
const char test_addon[50] = "CitSkins"; // Citizen Skins
void TestMountAddon()
{
char buffer[150];
sprintf(buffer, "Addons\\%s", test_addon);
MountAddon(buffer)
}
I've looked up 'Privileged Instruction' and found this:
'Now Privileged Instruction -
Win32-based applications that call inp(), outp(), and so forth can be
successfully compiled and linked. However, these applications will
generate the privileged instruction exception because the port I/O
functions cannot be called from code running in user mode.
Do not call the following functions from within a Win32-based
application executing in user mode:
_inp()
_inpw()
_inpd()
_outp()
_outpw()
_outpd()'
Which seems to be in accord with what I've found on MSDN (if with more
functions that are marked 'privileged').
I'm stumped: Why does calling AddSearchPath cause a privileged
instruction error? (Perhaps I'm just being stupid and missing the
obvious right now...)
