Question

I am using C language and Linux OS as my programming platform. And I want to know how can I make a read-only folder programmatically? Is there any mkdir command in C language for Linux or Unix-like system?

Thanks.

The way to do it is to use mkdir(2) to create the folder, populate it with the files you want it to have, use stat(2) to get the current permissions, mask out the write bits, then use chmod(2) to set the permissions.
