The DHCP_CLIENT_INFO_PB_ARRAY structure encapsulates an array of DHCP_CLIENT_INFO_PB (section 2.2.1.2.115) structures.

 typedef struct _DHCP_CLIENT_INFO_PB_ARRAY {
     DWORD NumElements;
     [size_is(NumElements)] LPDHCP_CLIENT_INFO_PB *Clients; // array of pointers
 } DHCP_CLIENT_INFO_PB_ARRAY, *LPDHCP_CLIENT_INFO_PB_ARRAY;

NumElements: The number of elements in the Clients member.

Clients: An array of pointers to DHCP_CLIENT_INFO_PB structures.
