Solved [Solved] C: Changing a file's attributes

[cenu]

Hello, I've been making some significant progress with my program for writing encrypted file archives. But I'm having a bit of trouble. I don't know how to change a file's attributes once it's been created, i.e. modification timestamp, UID, GID, mode, and size.) This part is extremely crucial for the file extraction process. Even redirection to 'man 2' or 'man 3' pages will be of great assistance.

Thanks in advance.

I think you are looking for chmod

man chmod

No, you misunderstood.
I'm looking for functions and/or system calls in the standard C Library, not shell commands.
Stuff like

man 2 chmod && man 2 chown

(found)
But I stilll need something to change the modification timestamp.

Try with:

man 2 stat && man 2 utimes

man 2 stat

Thanks. It's through that command that I was able to find the

utimes

system call will help.
