This structure is used to describe the type of a variable, the return type of a function, or the type of a function parameter.

Syntax

typedef struct FARSTRUCT tagTYPEDESC {
  union {
    ESC FAR* lptdesc;
    struct FARSTRUCT tagTYPEDSC* lptdesc;
    struct FARSTRUCT tagARAYDESC FAR* lpadesc;
    HREFTYPE hreftype;
  } UNION_NAME(u);
  VARTYPE vt;
} TYPEDESC;

Members

• lptdesc
  VT_PTR, the type to which this instance points.

• lpadesc
  VT_CARRAY.

• hreftype
  VT_USERDEFINED, can be used to retrieve type information for a user-defined type using the ITypeInfo::GetRefTypeInfo method.

• vt
  Type of the variable represented by this instance.

Remarks

If the variable is VT_SAFEARRAY or VT_PTR, the union portion of the TYPEDESC contains a pointer to a TYPEDESC that specifies the element type.
