HvCallGetNextChildPartition

HvCallGetNextChildPartition enumerates child partitions of the calling partition. This hypercall allows a parent partition to discover and iterate through all of its child partitions.

Interface

HV_STATUS
HvCallGetNextChildPartition(
   _In_  HV_PARTITION_ID  ParentPartitionId,
   _In_  HV_PARTITION_ID  PreviousChildPartitionId,
   _Out_ HV_PARTITION_ID* NextChildPartitionId
);

Call Code

0x0047 (Simple)

Notes

• Specify HV_PARTITION_ID_INVALID for PreviousChildPartitionId to start the enumeration.
• Set PreviousChildPartitionId = NextChildPartitionId to get the next partition.
• The hypercall returns HV_PARTITION_ID_INVALID when there are no more partitions to enumerate.

Input Parameters

Name	Offset	Size	Information Provided
ParentPartitionId	0	8	Parent (or SELF)
PreviousChildPartitionId	8	8	Last returned child or HV_PARTITION_ID_INVALID

Output Parameters

Name	Offset	Size	Information Provided
NextChildPartitionId	0	8	Next child or HV_PARTITION_ID_INVALID if end
