The DHCP_POL_EXPR_ARRAY structure specifies the array of expressions of a policy.

 typedef struct _DHCP_POL_EXPR_ARRAY {
   DWORD NumElements;
   [size_is(NumElements)] LPDHCP_POL_EXPR Elements;
 } DHCP_POL_EXPR_ARRAY,
  *PDHCP_POL_EXPR_ARRAY,
  *LPDHCP_POL_EXPR_ARRAY;

NumElements: This member is of type DWORD and contains the number of expression elements in the array.

Elements: This member is a pointer of type LPDHCP_POL_EXPR (section 2.2.1.2.107) that points to an array of DHCP_POL_EXPR (section 2.2.1.2.107) elements.
