Returns B_OK, if successful, B_ENTRY_NOT_FOUND, if the index is out of
range.
identify_module():
-----------------
Returns whether the module knows the supplied identifier. The module to
be used to partition a session is identified by this identifier.
params:
identifier: the identifier
Returns true, if the module knows the identifier, false otherwise.
get_partitioning_params():
-------------------------
Returns parameters for partitioning the supplied session.
If the session is already partitioned using this module, then the
parameters describing the current layout will be returned, otherwise
default values.
If the supplied buffer is too small for the parameters, the function
returns B_OK, but doesn't fill in the buffer; the required buffer
size is returned in actualSize. If the buffer is large enough,
actualSize is set to the actually used size. The size includes the
terminating null.
params:
deviceFD: a device FD
sessionInfo: a complete info about the session to be partitioned
buffer: pointer to a pre-allocated buffer of size bufferSize
bufferSize: the size of buffer
actualSize: pointer to a pre-allocated size_t to be set to the
actually needed buffer size
Returns B_OK, if the parameters could be returned successfully or the
buffer is too small, an error code otherwise.
partition():
-----------
Partitions the specified session of the device according to the supplied
parameters.
params:
deviceFD: a device FD
sessionInfo: a complete info about the session to be partitioned
parameters: the parameters for partitioning
Returns B_OK, if everything went fine, an error code otherwise.
