For example It can’t read this path: I was wondering if there is a possible way to read such a path which might be independent from the current working directory in other cases ? fopen () can take absolute paths as arguments.

Where does the generated pathname go in realpath?

The generated pathname shall be stored as a null-terminated string, up to a maximum of {PATH_MAX} bytes, in the buffer pointed to by resolved_name. If resolved_name is a null pointer, the behavior of realpath () is implementation-defined.
