33 * Creates system device "\Device\CaptiveHarddisk%d" providing readwrite access
34 * to the given #captive_image_iochannel as emulation of harddisk driver.
35 * reactos initializes "\Device\Harddisk%d\Partition0" as the whole disk
36 * and each partition it founds by IoReadPartitionTable() it will create
37 * as "\Device\Harddisk%d\Partition1", "\Device\Harddisk%d\Partition2" etc.
39 * libcaptive does not (yet?) support any partitions and it will always create
40 * just the disk device for the whole given #captive_image_iochannel.
41 * As this behaviour is a bit specific we rather create some non-standard name
42 * of the device; anyway I have seen some "\Device\Harddisk%dVolume%d" on W32
45 * captive currently supports just one drive and thus "\Device\CaptiveHarddisk0"
46 * is always created. It is forbidden to call this function twice.
48 * Returns: %TRUE if the initialization was successful.
