RE: [Dev-C++] How to get application directory?

[P.D. v. Z. <pa...@my...>]

For the original poster: Don't know if it will help you, but in Win32 I get
the path to the running application like this:

char szBuf[512];
GetModuleFileName(NULL, szBuf, 512);

(if the call succeeded, szBuf now contains the full path to the current
module (executable))

To Per:
Thanks :D I forgot that lots of things are file (or pseudo-file) based in
Linux. But it appears that /proc/self/exe is a symlink to the current
binary... which brings me to a second problem: How do I get the target of a
symlink as a string or something :) Whenever I'm programming for Linux I
constantly run into problems, cause I have no clue where to get MSDN-like
information for Linux or POSIX.

Regards,


Paul

If the application was started with a path, you might retrieve it as
the arg[0] parameter of main().

If not, you have to search the path for an application with the correct
name. I don't think there is a standard function to perform this. If I'm
wrong, I very much want to know the name of the function, since it would
be useful :)

On Linux, it is possible to heck in the /proc filesystem. There exists a
symbolic link:
/proc/<process_id>/exe -> /my/running/binary
That will specify which binary that is running.

It may also be accessed as:
/proc/self/exe -> /my/running/binary
to avoid the extra trouble of retrieving process id and dynamically create
the path to the symbolic link.
