Learn about MiG and how to write RPCs. There is a lot you can find on
the wiki and through search engines. If possible, don't create an
ioctl-style of call, with many possible behaviours through the same
entry point, but make several distinct RPCs instead, then add them to
include/mach/gnumach.defs. Look at how it's done for existing RPCs, but
make sure you read and understand the documentation about MiG and Mach
IPC if you want to work on such low-level stuff.
