Constants

 
VDS_ASYNCOUT_UNKNOWN
Value: 0
The value is reserved.
VDS_ASYNCOUT_CREATEVOLUME

Remarks

The VDS_ASYNC_OUTPUT structure includes a VDS_ASYNC_OUTPUT_TYPE value as a member to indicate an operation type.

Note  Additional constants might be added to the VDS_ASYNC_OUTPUT_TYPE enumeration in future Windows versions. For this reason, your application must be designed to gracefully handle an unrecognized VDS_ASYNC_OUTPUT_TYPE enumeration constant.
