Determines if the option(s) is set for
dev_t
io_legacy_to_new_dev()
Maps a legacy
dev_t to an agile dev_t
io_legacy_to_new_dsf()
Maps a legacy device special file to a persistent device special file
io_legacy_to_new_hwpath()
Converts the data structure of a pre-HP-UX 11i V3 hardware path
to that of the hardware path for HP-UX 11i V3 or later.
io_mkdev() Builds a dev_t, given a node and option string
io_mkdev_ext() Returns a
dev_t for the given node, dev_type, and device options
io_new_to_legacy_devs()
Maps an agile dev_t to one or more legacy dev_t(s)
io_new_to_legacy_dsfs()
Maps a agile device special file to one or more legacy device special
file
io_new_to_legacy_hwpath()
Converts the data structure of a hardware path used on HP-UX 11i
V3 or later to that of a pre-HP-UX 11i V3 hardware path.

io_search()
Searches I/O subsystem data structures
io_search_array()
Searches I/O system data structures
io_search_array_batch()
Retrieves an array of token matching the search
