Browsing through /usr/include/sys/* in search of clock tick values, I stumbled on a number of parameters for ioctl() calls pertaining to disk format operations. Are these documented anywhere? If so, where? If not, why are they not documented? I have a version of tar that runs under **IX and MSDOS, and one feature that I would like to add is the ability to detect unformatted disks and format them on the fly. While this could be done with a system() call, I'd like to do something a bit more elegant (and a bit faster).
