The BooleanArray structure is defined as follows.

 typedef struct _BooleanArray {
   [range(0, MAX_RPC_BOOL_ARRAY_COUNT)] 
     DWORD count;
   [size_is(count)] boolean* ptr;
 } BooleanArray;

count: A 32-bit unsigned integer that contains the number of BOOLEAN values pointed to by ptr.

ptr: A pointer to an array of BOOLEAN values.
