Memory handling can come from overriding operators new and delete in your
driver in terms of kmalloc and kfree. Anyway, who says that the driver has to
use new and delete? If they are not used, then the run time support won't be
required, any more than malloc, calloc, realloc and free required by
drivers written using C.
>And the exception handling? Got it yet?
Run-time exception handling support is not required by g++ generated code
unless you use the language feature.
The real problem is that nobody has sanitized the kernel header files
for use in C++.

Why not? Maybe he already has a class that implements a significant part of
the driver logic.

We were under the impression that glibc 2.1 should be a minor
increment to glibc 2.0 -- well not. So much for this reasoning.
And yes, that is my reason for still running a glibc2.0 system
with a fairly old egcs and glibc version -- if it ain't broken
don't fix it!
(interpretating ain't broken as: works for me without problems.)

Subject: SEND_FD ioctl?
Date: 13 Apr 2000 07:48:07 +0200
Hi,
I recently came across the need to pass a fd from one process to another.
"Advanced programming in the Unix environment" gave me an answer with an
ioctl called sendfd. I searched /usr/include and /usr/src/linux and didn't
find it. Does this thing exist in Linux or how do I emulate this behaviour?
Thanks,
Konstantin

Subject: GUS PnP and Linux 2.2+
Date: 13 Apr 2000 17:48:06 GMT
I am having a problem getting the kernel to recognize my GUS PnP. Under
kernal 2.0.38 using isapnp it worked fine. Also, using the commercial OSS
driver it does work, but not all that well. For example, the mixer won't
control the mic input volume.
Specifically, following the linux/Documentation/sound/ultrasound documentation
I get the following error:
/lib/modules/2.2.14/misc/gus.o: init_module: Device or resource busy
when I try to load the sound module.
The following is the output from loading the commercial OSS drivers. Note
the resources addigned to the GUS card. I then rebooted the system
(including a power off) and tried to load the kernel drivers. No joy.
Output from that attempt is at the end of the file. (After the ======)
Any help appreciated.

Subject: boot disk

I am trying to install redhat 6.1, but the boot disk I created
boots, and starts and shows me the main menu. Once I select an option,
it starts to load and once it gets to the second file I get an error.
Does anyone know how I could get around this? Or what I could possibly
be doing wrong.

Subject: is linux 2.3 available?
Date: 13 Apr 2000 17:43:49 GMT
Hi,
I got a (experimental) package and it requires linux kernel 2.3. I
have seen some discussion about kernel 2.3 but I could not find it!
The latest version I found was 2.2.14 from redhat and slackware. Can
anybody help me figure out where to find 2.3? Is it stable enough to
try?
Thanks a lot!
Have a nice day.
