Thread: info: mkdir(const char *path)

Hello :-)

I'm an engineer (mechanic) so Cprogramming is not my job, and my question can sound silly
to most of you. Please understand and thank you in advance.

My problem is:

I get a FileList.txt on argv[1], for example:

C:\F00\Pippo_Folder\Pippo_Data\PippoData001.dat
C:\F00\Robin_Folder\Robin_Data\RobinData005.dat
C:\F00\Batman_Folder\Batman_Data\BatmanData100.dat
etc..

I want to fopen(_argv[1],"r") then fopen(first_file,"rb"); and that's OK, I can do that.

My problem is that after reading the file I need to create a NewFile.dat with the same name
and "same Path" but to a new folder, for example i need this kind of output:

C:\F01\Pippo_Folder\Pippo_Data\PippoData001.dat
C:\F01\Robin_Folder\Robin_Data\RobinData005.dat
C:\F01\Batman_Folder\Batman_Data\BatmanData100.dat

(note F00 changed to F01..)

of course when i try to fopen(NewFile_in_NewPath,"wb") i get my warning
"cannot open file.." .. beacuse the NewPath doesn't exist yet.(I think)

So i tried to use the function mkdir(const char *path) but i cant get it right
It seem not so easy( to me ) to automatically create folders from C code.


Any tips ?
ThankYou Paolo

I didnt write yet the code to build the string I need, at the moment ( just to try mkdir function ) I wrote this code taking the info from my compiler (DevC++)

Code:

#include <stdio.h>

int main()
{
   const char path[256] = "c:\\F01\\New";
   if (mkdir (path) != 0) printf("Fail Retry");
   return 0 ;
}

And simply doesn't create anything.
I tried to find info or examples but the much info I get the more confused I am.
Some examples I found where very tricky and full of flags; Is really this difficult?

Thanks P

Thanks ! You make me Happy
