Is there anything I can do with an inode except check file identity within
a filesystem?
Can I, for example open a file for reading or writing
or read a directory given the inode number
instead of the full pathname?
I mean, as a programmer in user or superuser mode,
not running my own code inside the kernel.

AFAIK the only thing you can do with an inode is to check that two
files are actually hardlinks to the same file. You cannot open it and
you cannot obtain any information on it, including the filename. There
seems to be no function in the libc, and probably no system call which
takes the inode as an input parameter.
