Thread: Creating Folders using C

maybe my question is quite simple, but although searching like wild I cannot
find a solution.
I just want to create a file, let's say to "c:\my folder\filename1.txt".

Normally with append-option, the file is created if it doesn't exist. But I
want also the folder to be created if it does not exist - now if the
specified folder is not available, the file isn't created at all.

Is there an additional option in fopen or orther function that could do exactly this?

I am using Windows-7 OS and MS Visual C++ compiler. I want to do this using C language without using system() function.

CreateDirectory Function (Windows)

I want to work using C language !!! can u give me a short example of how the above function works ??

This is a C function, it is part of the Windows API (Application Programming Interface) provided to give you access to operating system functions... just like the strings library adds strings to the basic language.

Code:

#include <windows.h>

int main (void)
  {  char *NewDir = "coppers";

      CreateDirectory(NewDir,NULL);

      return 0; }

It's just that easy...

Hello Mr. anduril462,
I know, probably you are a very good programmer .... or maybe I am talking to future bill gates...you might be working on this things for years...... but dude ...I have started working on this thigs for only a month or so ..... it will take time !!!!!! ok !!! I know my questions might be a little immatured!!!! but it requires patience to learn things !!!!!!! and I try to keep it !!!!!!! hope u will understand!!!!

Are they responding to a signature?

Exclamation marks are like cats. Having a few is fine, but more than about three makes you look completely unhinged.

you could also use the system() function in stdlib.h and use cmd line commands to check for, and make dirs. at least i think that would work.

Why would you want to do that when the Windows API is ten times faster and has everything you need?

It would appear so...

lol that question again, well, maybe the op would want a list of available possibilities, im just saying he can do that, im not saying it is the best way to do it. At least i know that when try to reach something i like to know every path available, for education porposes mainly. For instance, now, and because i brought this up, op knows that using the windows API is faster, see?? Win win

Ok, point taken...

However, you could have also mentioned that you way would be slower...

system("mkdir") would also be portable (mkdir works on Linux too), would create intermediate directories and would cleanup after itself on failure. To do that (minus portability), your one line CreateDirectory just turned into 10.
