I suspect you can't deal with that. Which isn't to say you can't still build something useful. The query interfaces are trivial enough and beyond that it's simply a case of documenting that they are not intended to be generically "safe" but provide a spot sample.
Otherwise - TICOGPKT is specific to pty devices. Please therefore put it in the pty.c code and note that not all platforms use asm-geneic TTY ioctls so check carefully they all build.
