Using a C program to create directories in UNIX

Aloha,

I'm attempting to use a C program to create directories and then use a system call to have another program write .dat files into that directory. I understand that I could use the "system("mkdir directory_name")" function however, I would like my program to create a new directory each time the program loops by incrementing an integer contained in the file name each loop. Here are some example directory names: A1, A2, A3, A4, A5...

I know that this isn't the proper use of the system function, but below is some code that might better illustrate what im trying to do.

main()
{
int i;
for(i=0;i<5;i++)
system("mkdir A%d",i);
}

I also don't mind using a string of characters in an array that I would modify each time I pass through the loop and use as the directory's name.

Does anyone know of a simple way to have a C program create unique directories each time it passes through a loop, by incrementing an integer contained in the file name?

Mahalo,
Windell

sticky

STICKY(7)					       BSD Miscellaneous Information Manual						 STICKY(7)

NAME

     sticky -- sticky text and append-only directories

DESCRIPTION

     A special file mode, called the sticky bit (mode S_ISTXT), is used to indicate special treatment for directories.	It is ignored for regular
     files.  See chmod(2) or the file <sys/stat.h> for an explanation of file modes.

STICKY DIRECTORIES

     A directory whose `sticky bit' is set becomes an append-only directory, or, more accurately, a directory in which the deletion of files is
     restricted.  A file in a sticky directory may only be removed or renamed by a user if the user has write permission for the directory and the
     user is the owner of the file, the owner of the directory, or the super-user.  This feature is usefully applied to directories such as /tmp
     which must be publicly writable but should deny users the license to arbitrarily delete or rename each others' files.

     Any user may create a sticky directory.  See chmod(1) for details about modifying file modes.

HISTORY

     A sticky command appeared in Version 32V AT&T UNIX.

BUGS

     Neither open(2) nor mkdir(2) will create a file with the sticky bit set.
