TYPEATTR

Contains attributes of an ITypeInfo, and is defined as follows:

typedef struct FARSTRUCT tagTYPEATTR {
    GUID guid;                    // The GUID of the type information. 
    LCID lcid;                    // Locale of member names and doc 
                                // strings.
    unsigned long dwReserved;
    MEMBERID memidConstructor;    // ID of constructor, or MEMBERID_NIL if 
                                // none.
    MEMBERID memidDestructor;    // ID of destructor, or MEMBERID_NIL if 
                                // none. 
    OLECHAR FAR* lpstrSchema;    // Reserved for future use.
    unsigned long cbSizeInstance;// The size of an instance of 
                                // this type.
    TYPEKIND typekind;            // The kind of type this information
                                // describes.
    unsigned short cFuncs;        // Number of functions.
    unsigned short cVars;        // Number of variables/data members.
    unsigned short cImplTypes;    // Number of implemented interfaces.
    unsigned short cbSizeVft;    // The size of this type's VTBL.
    unsigned short cbAlignment;    // Byte alignment for an instance 
                                // of this type.
    unsigned short wTypeFlags;
    unsigned short wMajorVerNum;    // Major version number.
    unsigned short wMinorVerNum;    // Minor version number.
    TYPEDESC tdescAlias;            // If TypeKind == TKIND_ALIAS, 
                                // specifies the type for which 
                                // this type is an alias.
    IDLDESC idldescType;        // IDL attributes of the 
                                // described type.
} TYPEATTR, FAR* LPTYPEATTR;
 

The cbAlignment field indicates how addresses are aligned. A value of 0 indicates alignment on the 64K boundary; 1 indicates no special alignment. For other values, n indicates aligned on byte n.
