identify():
|
|
----------
|
|
|
|
Checks whether the partition map of the given session can be recognized
|
|
by the module. Returns true, if it can, false otherwise.
|
|
|
|
params:
|
|
deviceFD: a device FD
|
|
sessionOffset: start of the session in bytes from the beginning of the
|
|
device
|
|
sessionSize: size of the session in bytes
|
|
block: the first block of the session
|
|
blockSize: the logical block size

get_nth_info():
|
|
--------------
|
|
|
|
Fills in the following fields of partitionInfo with information about
|
|
the indexth partition on the specified session:
|
|
* offset
|
|
* size
|
|
* flags
|
|
* partition_name
|
|
* partition_type
|
|
* partition_code
|
|
|
|
params:
|
|
deviceFD: a device FD
|
|
sessionOffset: start of the session in bytes from the beginning of the
|
|
device
|
|
sessionSize: size of the session in bytes
|
|
block: the first block of the session
|
|
blockSize: the logical block size
|
|
index: the partition index
|
|
partitionInfo: the partition info
|
|
|
|
The functions is only called, when a call to identify() returned
|
|
true.
|
|
|
|
Returns B_OK, if successful, B_ENTRY_NOT_FOUND, if the index is out of
|
|
range.
