I'm trying to figure out a way where I can change my current output directory using C++ code - and also need that method to be platform agnostic.
I found the direct.h header file which is Windows compatible, and the unistd.h which is UNIX/POSIX compatible. Any solutions?
Both implementations return zero on success and -1 on error. As you can see in the manpage, more distinguished errno values are possible in the POSIX variant, but that shouldn't really make a difference.
