Hi,
I was wondering if there was a way to know the absolute path of the
library "currently running".
For example, in my function foo, how can I get the path of the library
containing the definition of foo?
The library path will be different from the "current directory" (.)
since the current directory will be the directpry of the prgram that
loaded the lib; not the path to the library itself.
Otherwise, do you know fi the STL library provide a "registry service"
(like the java Preferences API)?
Thanks a lot for your help

That's very platform specific, some platforms might not even have
libraries or directories.
Better ask on a group specific to your platform.

No.

There can be. However, it would be a feature of the OS, not of the
language.
In C++ what's "running" is the program, not "the library". The host system
_may_ provide the command with which it was started, in the 'argv[0]' (see
the 'main' function), or it may not, it's up to the system. Many systems
do,
yet some don't.
For example, in my function foo, how can I get the path of the library
containing the definition of foo?
C++ defines the _language_. In C++ you can find the _translation unit_ in
which the *code* is contained (see __FILE__ macro). The rest is platform-
and implementation-specific (and off-topic here).
The library path will be different from the "current directory" (.)
since the current directory will be the directpry of the prgram that
loaded the lib; not the path to the library itself.
All those things are unknown to C++.

Nothing like that in the Standard.

on unix : ldd ./a.out (./a.out is the executable )
macosX : oTool ./a.out

In unix type the following command :
$ ldd <executable name>
If you want to attach the libraries at the time of running, you have
update the LD_LIBRARY_PATH

Hi there.
I have an included file (header.php) that contanis a reference to a graphic.
If I stay at the root level, then I can control the relative path of the
image.
eg. images/imagename.jpg
However, if I include this file (header.php) in a lower level directory then
of course, I end up with no image displaying as the relative path is no
longer correct.

Hi All,
I got a challenge to make the same APS/Script/Html run on different web
roots. I can not use relative pathing in a lot of cases. We use lots of
included files so depending on where that file is running, the pathing in
those included files varies. So we do a lot of absolute pathing.
Example: Instead of Mappath("../../../_scripts/menu/mymenuscript.js") we use
mappath("/_scripts/menu/mymenuscript.js").
In one case, the code is...

The Problem is that the following Connection string
