Keep getting an “invalid argument” error when using Luigi Auriemma’s uif2iso after compiling on Mac OS X? In a nutshell, you will have to use “fseeko” instead of “fseek”, and “ftello” instead of “ftell” in his uif2iso.c file, when compiling in OS X.

I have made the appropriate changes (uif2iso.c), as well as fixed the warnings (version 0.1.2). I have made a diff of my changes also (uif2iso.diff.txt).
