Getting current path?

**Blackroot** · 01-26-2006

Ok, I admit, I'm a lifeless geek that is absolutely addicted to programming. Unfortunantly, that doesnt mean I'm good at it :P.

So, I have a bit of a conundrum. I want to pick up a file in a subdirectory of where my .exe is being run from. I know I can do this:

Code:

ofstream hi("file.extension", extra stuff);

But my file is not located in the same directory as my exe, its in a sub directory. So, is their some way to throw the current path into a buffer?

Code:

string h;

h=CurrentPath();

And what library does/would it use?

For windows you would use GetCurrentDirectory() which is from the windows.h header file.

It has 2 parameters, the first you use MAX_PATH.

The second parameter is the buffer you would like to store the current directory in.

It should look like

GetCurrentDirectory(MAX_PATH, buffer);

The path of program will be sent to it as the first main(int argc, char* argv[]) argument.

If it is run from the command line it will just output the filename like "program.exe".

However if the file is double clicked, then argv[0] will hold the current path aswell as the program name.

In this case it will hold the full path to the exe. But that need not be the current working directory.
You have to call somthing like GetCurrentDirectory() to find out the current working directory.
Even if you call your exe from the commandline. You could call the exe from anywhere ( somwhere other then where the exe is located ) and your OS would locate the exe via the PATH environment variable.
