Need help with QNX4FS

Help me please! I am a student and I must write a program which will draw map of a disk with qnx4fs. But I can’t find information how to distinguish file or directory. In qnx4fs_dir_entry union in qnx4fs_inode_info structure there is a i_type field but I cant’t find what flags what meaning :frowning: .

There’s an overview of the QNX 4 filesystem in the Backing Up and Recovering Data chapter of the Neutrino User’s Guide, but it doesn’t go into all the details.

I saw it doc but there are not much usefull for me. However thanks for reply.
