    Force relative paths

    Hi in my program there is an option to enter a directory as a command line argument. Is there any check I can perform to see whether this directory is relative to the current working directory?

    For example if we are /home/user and the user wants to input /home/user/folder they have to type ./folder.

    I need this to keep folder structure. Failing this is there anyway which I can compare two strings to produce the relative paths.

    For example I will always have the current working directory in absolute stored in 'cwd' and I will also have the absolute path of the user entered directory stored in 'folder'

    Can I compare the two and produce a relative path of 'folder' from 'cwd'?

    Thanks for your help

    Edit: This program is intended for Ubuntu Linux btw

    Absolute paths start with /

    Relative paths don't.

    Cheers. Never even thought about that, been racking my brain for ages.

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
