Handle to prom returned by di_prom_init().

For device nodes whose nodeid value is DI_PROM_NODEID (see di_nodeid(3DEVINFO)), additional properties can be retrieved from the PROM. The di_prom_init() function returns a handle that is used to retrieve such properties. This handle is passed to di_prom_prop_lookup_bytes(3DEVINFO) and di_prom_prop_next(3DEVINFO).

The di_prom_fini() function destroys the handle and all handles to the PROM device information obtained from that handle.

Upon successful completion, di_prom_init() returns a handle. Otherwise, DI_PROM_HANDLE_NIL is returned and errno is set to indicate the error.

The di_prom_init() sets errno function to any error code that can also be set by openprom(7D) or malloc(3C).
