Hi Paul,
Thanks alot for your hint! I'm a bit new to API and I don't know with c++ if
I have to declare this function (GetModuleFileName()) in a header or what I
do have to do in order to being able to use this function you describe.
Could you help me on that too? (If I need a function declaration in my
header, could you please post it with the right variable types or point me
to a website where i can find those API function declarations???)
Thanks again,
Josep
BTW,
I've tried with the following code, but I don't know if the *working
directory* is always, at the beginning, the same as the directory where the
.exe file lies!!!
const long size = 1000L;
char *buf;
char *cwd;
//size = pathconf(".", _PC_PATH_MAX);
cwd = getcwd(buf, (size_t)size) ;
char flag[size] = "--datadir=";
char *subdir = "\\data";
char *foo = strcat (buf, subdir);
strcat(flag, foo);
int argn = 3;
char *arg[] = {
argv[0], "c++", flag
};
mysql_server_init(argn, arg, (char **)server_groups);

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