Get the path of the executable file

[santaris]

Hello.Is there any function to get the exact path where the executable is even if the executable path changes.I mean that i run the executable in a different path everytime.Thanks in advance.

Yes.

    string fullFileName = "";

    // Code taken from: http://www.gamedev.net/community/forums/topic.asp?topic_id=459511
    std::string path = "";
    pid_t pid = getpid();
    char buf[20] = {0};
    sprintf(buf,"%d",pid);
    std::string _link = "/proc/";
    _link.append( buf );
    _link.append( "/exe");
    char proc[512];
    int ch = readlink(_link.c_str(),proc,512);
    if (ch != -1) {
        proc[ch] = 0;
        path = proc;
        std::string::size_type t = path.find_last_of("/");
        path = path.substr(0,t);
    }

    fullFileName = path + string("/");

I assume that you're running linux!

Then just type

path = system("echo $PWD");

and your path will hold the current directory where executable is!

Just try it in your terminal type echo $PWD you'll see!

Don't use the "system()" function.
Do it the way Zaita showed you.

Possibly you could pipe the output of something like "ls" with a childprocess and execvp or something, but Zaitas way is already there and probably better.

Probably!
