All of those functions exist on MPE and I believe they all live in libc.  I've
never used the HP C/iX compiler, but with with freeware gcc you don't need
any special link-time switches or to include any explicit libraries for the
functions listed above.

Note that many POSIX functions on MPE require you to compile with
-D_POSIX_SOURCE to get the proper include definitions.

Also note that MPE ioctl() almost certainly has fewer supported opcodes than
standard Unix ioctl().
