Hey, why does this code have a problem? Heres my code:

  
else if(ipt1 == mdir)
	{
		int sec1;
		int sec2;
		int sec3;
		int sec4;
		char dmem[180];
		GetCurrentDirectory(180, dmem);
		GetDiskFreeSpace( dirname, sec1, sec2, sec3, sec4);
		cout << " " <<  dmem << "...." << endl;
		return(main());
	}

Here are my error''s

  --------------------Configuration: Sathenzar - Win32 Debug--------------------
Compiling...
Sathenzar.cpp
C:\demonrealms\Sathenzar.cpp(312) : error C2664: ''GetDiskFreeSpaceA'' : cannot convert parameter 2 from ''int'' to ''unsigned long *''
        Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast
Error executing cl.exe.

Sathenzar.obj - 1 error(s), 0 warning(s)

And can you please NOT ask me why I''m returning main?? I don''t care about that. I just want to know why the section of code doesn''t work. (Not trying to be rude either) Thanks, Demon Realms Studios

The function seems to expect unsigned long* instead of int, so you need to change you declarations:

  
unsigned long sec1;
unsigned long sec2;
unsigned long sec3;
unsigned long sec4;

and call it with the adress of the vars:

  
GetDiskFreeSpace( dirname, &sec1, &sec2, &sec3, &sec4);

Hope that helps.

BTW, why are you returning main?

It sill comes up with these errors:

  Sathenzar.cpp
C:\demonrealms\Sathenzar.cpp(312) : error C2664: ''GetDiskFreeSpaceA'' : cannot convert parameter 2 from ''unsigned long'' to ''unsigned long *''
        Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast
Error executing cl.exe.

Sathenzar.obj - 1 error(s), 0 warning(s)

And this is my code now:

  else if(ipt1 == mdir)
	{
		unsigned long sec1;
		unsigned long sec2;
		unsigned long sec3;
		unsigned long sec4;
		char dmem[180];
		GetCurrentDirectory(180, dmem);
		GetDiskFreeSpace( dirname, sec1, sec2, sec3, sec4);
		cout << " " <<  dmem << "...." << endl;
		return(main());
	}

Never mind, it works now.

Yep, you missed the ''&''s in the function call, which generate the adress of the respective object they''re used on. This makes the argument a pointer.

sec1 is of type unsigned long
&sec1 is of type unsigned long*
