Dir creating, permissions setting issue!

Hello, I need to create some dirs (one for each user), taking the dir name from a given string.
I managed to do this with the following code:

C Syntax (Toggle Plain Text) 
  1. DIR *dir_ptr;
  2. char *target_dir;
  3.  
  4. target_dir = malloc(32*sizeof(char));
  5.  
  6. for(all users)  {
  7.  
  8.     /* Set username for current user */
  9.  
  10.     target_dir[0] = '\0';
  11.     strcat(target_dir, "./Environment");
  12.     strcat(target_dir, "/");
  13.     strcat(target_dir, username);
  14.     strcat(target_dir, "/");
  15.  
  16.     /* check for DIR existence, if not, create */
  17.     if((dir_ptr = opendir(target_dir)) == NULL)  
  18.         mkdir(target_dir);
  19.  
  20. }

My problem is these dirs are created with no permissions at all, I've got to set them manually doing "chmod 777 name", is there a function out there to create dirs with permissions already setted? I need to use them later from inside my application and I want the users to be able to modify them from the OS (ie adding files inside).
I use Debian, in XP no problems!

Apparently, mkdir() takes 2 parameters.
http://www.rocketaware.com/man/man2/mkdir.2.htm

One wonders whether
- you read the manual before calling it
- included the appropriate header file which would have warned you about too few parameters
- mis-took early success on other platforms as a sign of bug-free code.
