The SAFEARR_BSTR structure specifies an array of BSTRs (see section 2.2.23).

 typedef struct _wireSAFEARR_BSTR {
   ULONG Size;
   [size_is(Size), ref] BSTR* aBstr;
 } SAFEARR_BSTR;

Size: MUST be set to the total number of elements in the array.

aBstr: MUST be an array of BSTRs (see section 2.2.23).

Data of this type MUST be marshaled as specified in [C706] section 14, with the exception that it MUST be marshaled by using a little-endian data representation, regardless of the data representation format label. For more information, see [C706] section 14.2.5.
