5. Partitioner module

Partitioner module interface consists of three functions. These functions handle all requests of Part Module independently of used partition table type. The functions are following:

• The function int read_partitions(int filehandle, struct disk_info *diskinfo, ERR_PARAM); reads in a partition table from the device. This function is capable of detection of used partition table type.
• The function int commit_partitions(int filehandle, struct disk_info *diskinfo, int checkonly, ERR_PARAM); analyzes the designed changes in the partition structures, checks that partition table can be created for the proposed changes and if not invoked in `check-only' mode modifies the partition table.
• The function int dirty_partitions(struct disk_info *, struct disk_info *, ERR_PARAM); analyzes the designed changes in the partition structure and returns one iff the disk partition table has to be modified to reflect the changes.
