create directory

[Maurader]

how do i create directories on the harddrive from my program?

you can use:

#include<windows.h>
....
...
BOOL CreateDirectory(
  LPCTSTR lpPathName,                         // directory name
  LPSECURITY_ATTRIBUTES lpSecurityAttributes  // SD
);

example:

CreateDirectory(&quot;c:\\my directory&quot;, NULL);

or you might also use:

#include<direct.h>
....
...

int _mkdir( const char *dirname );

example:

_mkdir(&quot;c:\\my directory&quot;)

is there a way to check if the directory already exists? or is it necessary?

Just call the mkdir function or any other function and check for its error code. If the creation was a succes, then you can delete the directory you just created, if you just wanted a check. Else, an error is returned.

I don't know any other means to check for something like that (at least, no ANSI ways). [red]Nosferatu[/red]

#include <windows.h>

DWORD dwAttrs = GetFileAttributes ( &quot;C:\\Is\\This\\A\\Dir&quot; );
if ( dwAttrs == 0xffffffff )
{ // failure of GetFileAttrs
} else
{ if ( dwAttrs & FILE_ATTRIBUTE_DIRECTORY )
{ // It is a directory
} else
{ // It exists, but is not a directory
} }

Duh...
Yep Marcel... That brings me to another idea... why not use stat function? I completely forgot about it, so I'd redflag my previous post :-( [red]Nosferatu[/red]

if &quot;CreateDirectory&quot; returns 0 than it means that this function has fail,there could be many reasons.
One of these reasons could be because the directory already exist.

And for &quot;_mkdir&quot; if it return -1 it means that the function has fail.It could be for the same reasons than before.

&quot;_mkdir&quot; will return 0 if it succeeds and &quot;CreateDirectory&quot; will return 1.
