2.0.36, but that could change if 2.2 solves the problem.

Uh, oh. Does that mean that it takes a special CD-ROM reader to do this?

Thanks for the hint. I will RTFM.

Subject: listing symbols in a dynamic library
Date: Sat, 08 May 1999 22:50:57 GMT
Is there a way to get a list of the symbols found in a dynamic
library that has been opened with dlopen()? Might there be some
reserved symbols that references a structure with all the symbols?
The reason I want to get the list is so that my program can add
the symbols to a menu of options that the user can choose from.
For example, suppose I have a program that prepares graphical
images, and I want to support pluggable export filters implemented
as functions named "export_<arbitrary>_<method>". The range of
values for <method> would be known in advance, but not the range
of values for <arbitrary>. What the program might do is for each
such name found, lookup "export_<arbitrary>_get_menu_desc" and
call it to get back a string to fill in on the pop-up menu.
I don't want to have to require every different pluggable to be
a different library. But if there is no solution to get the list
of names, then I guess that would be the common practice (do you
know if that indeed is the common practice?).

I use a tulip card with no problems at all. However, I've noted that
there are tons of different tulip cards, each with subtle differences.
My particular card is sensitive to the version of the driver. With
the latest 2.0.37-pre?? kernels, the included driver works fine. With
the 2.2.x kernels, I have to install a different one from:
http://www.bmen.tulane.edu/~siekas/driver.html
Interestingly, 2.0.37-pre?? has a newer version of tulip.c than 2.2.6
(I haven't check 2.2.7). I would suggest trying several versions of
the driver before giving up on the card, especially if it works under
2.0 but not 2.2. You might even be able to use the 2.0 driver under
2.2--I'm not sure if there are any complications in doing so.

minor detail: I need a good PCI card, not ISA. 10/100 would be great,
but at least a clean 10 over PCI is minimal.

I have 3 varieties:

- a 'lite-on' pnic tulip clone
all 3 work identically. they work well for light traffic but under
heavy load (my ping flood, for example; or even a local rolled-cable
ftp at 100/full) the tulips lock up and need a system reboot. note
that the console (X, etc) is still alive and well; its just that the
net card goes out in the weeds and never comes back.)

the 'nm' program (part of the binutils package) can do just that; i'd check
the nm source code and see how it does it.

Even so, the vast vast vast majority of desktop users will not
grab a random binary from off the web. Glibc did not break any
'public' functions, only functions that are private to
glibc. The new distributions (at least RH 6.0) are
shipped with the 2.2 series kernel and glibc2.1. Stable
commercial binaries can take some time - months. Joe User will
grab new binaries when the next distro release comes out in
a year or so.

No one is tying RedHat or anyone else's hands. Competition will
make the distros comform to the end user. If you want to talk to
someone about what the end user wants from their distribution,
talk to them - they get paid to make Joe User happy.

Oops, I need to qualify further. I need to do it from within the program
as a function given the handle provided by dlopen(). At the level where
I need to do this, the file name won't be available, just the handle.

Hello Jack,
I know of two books to read for your project. The first is called
"Operating Systems Design and Implementation", also known a the Tannenbaum
book. In this book they discuss an OS called Minix. Linus Torvalds began
the Linux development project by building upon Minix. A large number of
Linux and UNIX developers started off by reading this book.
The other book is called "The design and implementation of the 4.4 BSD
operating system." In here the architects of the system talk about the
the design of the BSD kernel. A lot of mainstay features of UNIX were
developed by these folks.
Happy reading !

Eric,
Take a look at mgetty. It allows you to fairly easily set up your linux box
as a PP server - you can dial-in using anything that uses PPP (it also
allows vanilla serial dial-in). I have it running on my box at home, and can
dial-in using Windoze or Linux from my laptop.
Hope this helps
