    dwSize Returns the size of this structure.

    Note   All WSAQUERYSET members that are not specified in the table are reserved and must be set to NULL or zero (0) depending on the data type of the member.

    When it enumerates cloud names, WSAQUERYSET.lpBlob returns a result set in the PNRPCLOUDINFO. The following table shows the possible return values.

    PNRPCLOUDINFO members Description
    dwSize The size of this structure.

    • If enCloudFlags is not set, then the cloud name can be transferred to other computers.
    • PNRP_CLOUD_FLAGS specifies the valid values. Some cloud names are valid on any computer on the same network. Other cloud names are valid only on a current computer, and may be valid only for a period of time.
