[Dev-C++] rookie question... Getting the current directory

[Danny R. <dro...@ho...>]

Hi,

Just started today picking my programming hobby after 10 years when i =
used an amiga and a whole different programming
enviroment, i feel like a rookie again in the world of programming with =
c++ with dev4 & windows.....

Can someone tell me how to get the current directory, i think it would =
be something like this:

string test;

void main(void)
{

test =3D GetCurrentDir();



  return 0;
}

But ofcourse, this doesnt work.... someone.. enlighten me..

i tryed all kinds of material but couldn't find something that worked =
with dev4 and i dont know where i have to find the problem.

thanks for your help

Danny.

I didn't try this, but maybe it could work:

#include <stdlib.h>

void main(void)
{
    test=3Dsystem("cd");
}
Since your main function is declared as void, it shouldn't return =
anything.

Try getcwd():

  	  /#include/ /<unistd.h>/
	  /#include/ /<io.h> // <stdio.h> is standard but MinGW uses io.h/

	  /main()/
	  /{/
	       /char/ /*cwd;/
	       /if/ /((cwd/	/=/ /getcwd(NULL,/ /64))/ /==/ /NULL)/
	       /{/
		    /perror("pwd");/
		    /exit(2) <http://www.mcsr.olemiss.edu/cgi-bin/man-cgi?exit+2>;/
	       /}/
	       /(void)printf("%s\n",/ /cwd);/
	       /free(cwd);/
	       /return(0);/
	  /}/

The man page is at:
http://www.mcsr.olemiss.edu/cgi-bin/man-cgi?getcwd+3

Note that this is POSIX, Windows has their own non-portable API for 
directory and file operations.

Good luck!

----------------------------

Windows uses GetCurrentDirectory()

------- From docs ---------
The GetCurrentDirectory function retrieves the current directory for the
current process.

DWORD GetCurrentDirectory(

    DWORD  nBufferLength, // size, in characters, of directory buffer
    LPTSTR  lpBuffer  // address of buffer for current directory
   );
Parameters

Return Value

If the function succeeds, the return value specifies the number of
characters written to the buffer, not including the terminating null
character.

If the function fails, the return value is zero. To get extended error
information, call GetLastError().

If the buffer pointed to by lpBuffer is not large enough, the return value
specifies the required size of the buffer, including the number of bytes
necessary for a terminating null character.
------- End extract ---------

Hello!

> Windows uses GetCurrentDirectory()
Well, you have to be careful with this function, because it not always gives the 
directory, where the program executable is! Whenever you press enter (or 
double-click) on a file, which is associated to your program, then the current 
directory will be the dir, where the associated file is, NOT the dir of your 
exe! This can be annoying, when you want to write config-files. To retrieve your 
programs path, use __argv[0]. This contains the path to your program (for 
example: "C:\myprog\myprog.exe"). The other __argv[] elements contain the 
command-line arguments.

Hope that helps.
