/* These functions all take two callback functions as the first two arguments.
The first callback function USE_INIT_PORT is called as follows:
error_t use_init_port (int which, error_t (*operate) (mach_port_t));
WHICH is nonnegative value less than INIT_PORT_MAX, indicating which
init port is required. The callback function should call *OPERATE
with a send right to the appropriate init port. No user reference
is consumed; the right will only be used after *OPERATE returns if
*OPERATE has added its own user reference.
The second callback function GET_DTABLE_PORT should behave like `getdport'.
All these functions return zero on success or an error code on failure. */
