IFSMgr_MountChildVolume

IFSMgr_MountChildVolume(
 unsigned long VRP,
 unsigned long Drive
 )

This service is used to mount a child volume that is associated with a parent volume. Typically, compression drivers like DRVSPACE use this to create the host and child drives.

VRP

Supplies the system volume handle for the parent volume the child volume is associated to.

Drive

Supplies the 0-based drive number for the drive unit the child is to be mounted on.

• Returns 0 if success, errorcode if failure.

The IFS manager looks for a parent volume with the same system volume handle as the one passed in. If one is found, a drive mapping is created for the child volume and it is mounted.
