Describes the type of a variable, the return type of a function, or the type of a function parameter.

  union {
    struct tagTYPEDESC  *lptdesc;
    struct tagARRAYDESC *lpadesc;
    HREFTYPE            hreftype;
  } DUMMYUNIONNAME;
  VARTYPE vt;
} TYPEDESC;

Members

DUMMYUNIONNAME.hreftype

With VT_USER_DEFINED, this is used to get a TypeInfo for the UDT.
