It is a function that allows one to access one of the ports in the task's
initial port table conveniently (see hurd_ports_get, hurd_ports_set and
<hurd/hurd_types.h>).
Note that the macro is more generic than the function, which only allows
access to the init ports, while the macro allows any port (and is used like
this in glibc). Note also that the function itself is used as an argument
in the hurdlookup.c routines.
Thanks,
