Creating directories in Unix using C language

Hi
I need help writing a c program that would create N directories and start N processes that would prompt the user for a file name, which it would then create in its respective directory. We can use semaphores in the program. Any help is appreciated.Thanks.

create a directory:
mkdir(dirname);
creating processes: createProcess (win****)

creating threads is what you want!!!

on win**** there is a function to display the save-file dialog. i cant remember right now, sorry.
but it has a parameter to auto-create directories.

why do you want to use semaphores? i don´t think you need IPC... use threads instead (or a simple for-loop???)

Hi,
Thanks for the help. Threads would be an easier option but I need to use semaphores, to see how they work.
Thanks again
