The DNS_RPC_SKD_LIST structure contains the information about a list of signing key descriptors that are present for a particular zone on the DNS server.

 typedef struct _DnssrvRpcZoneSigningKeyList {
   DWORD dwRpcStructureVersion;
   DWORD dwReserved0;
   [range(0,1000)] DWORD dwCount;
   [size_is(dwCount)] PDNS_RPC_SKD SkdArray[];
 } DNS_RPC_SKD_LIST,
  *PDNS_RPC_SKD_LIST;

dwRpcStructureVersion: The structure version number; this MUST be set to 0x00000001.

dwReserved0: MUST be set to zero when sent and MUST be ignored on receipt.

dwCount: The number of signing key descriptors present in the array of signing key descriptors pointed to by SkdArray.

SkdArray: An array of structures of type DNS_RPC_SKD (section 2.2.6.2.1). Each element of the array represents one signing key descriptor.
