read the SDI description structure
boolean_t sdi_dev_read_opr( rm_key_t key,
obtains the SDI device description structure
from the resource manager database
and reads it into the specified buffer.
This structure completely describes
the SDI device.
``Resource manager database''Resource manager
typically made known to the driver
by a call to the driver's
entry point routine.
Pointer to a previously allocated
returns B_TRUE on success,
or B_FALSE if key is invalid.
is called any time a driver
wants to obtain a complete description
of an SDI device from a resource manager key.
For efficiency, it should be called
only from the
entry point routine of a driver
and its value cached.
Context and synchronization
Driver-defined basic locks, read/write locks, and sleep locks
cannot be held across calls to this function.
