Both of these methods seem rather more complicated than:

	currentDir := Lock("",AccessRead);

(I write in Modula-2, but I believe this will work the same in C)

Someone asked for an example of where the Amiga documentation is unclear. This
is an example - it is not at all clear from the documentation that passing
Lock the null string as a file name will get you the current directory.

Naturally, if anything above constitutes an opinion, I claim it.
