Thread: Dir where application resides

Hello All,

Im trying to get the working directory where my application resides. My actual code uses getcwd.

Code:

#include <unistd.h>
#include <limits.h>

main()
{
char *cwd;
char buf[PATH_MAX+1];
          if((cwd = getcwd(buf, PATH_MAX+1)) == NULL) {
                      perror("pwd");
                          exit(1);
          }
puts(cwd);
}

The result is the current working directory that my user is in the shell session.
If I do this:

cd /tmp
/home/user/cwd

the return is /tmp and not /home/user

Is there a way to get the working directory where the app resides and not the cwd where the user is ?

Thanks,

Ok anonytmouse, understood ! I'll try argv[0] for now and think in a better solution for the next versions !

Thanks for the help !

Hi iain,

I've tryed getwd but it has the same result as getcwd. My code:

Code:

#include <unistd.h>
#include <limits.h>

main()
{
  char buf[500];
  getwd(buf);
  printf("getwd: [%s]\n",buf);
}

The output was:
$ cd /home/user/tmp
$ ./getwd
getwd: [/home/user/tmp]
$ cd /tmp/
$ /home/user/tmp/getwd
getwd: [/tmp]
$

Thanks !
