Creates a property data object, that is, an IPropData object.

Header file:

Mapiutil.h

Implemented by:

MAPI

Called by:

Client applications and service providers

 
SCODE CreateIProp(
  LPCIID lpInterface,
  ALLOCATEBUFFER FAR * lpAllocateBuffer,
  ALLOCATEMORE FAR * lpAllocateMore,
  FREEBUFFER FAR * lpFreeBuffer,
  LPVOID lpvReserved,
  LPPROPDATA FAR * lppPropData
);

Parameters

  • lpInterface
    [in] Pointer to an interface identifier (IID) for the property data object. The valid interface identifier is IID_IMAPIPropData. Passing NULL in the lpInterface parameter also causes the property data object returned in the lppPropData parameter to be cast to the standard interface for a property data object.

  • lpAllocateBuffer
    [in] Pointer to the MAPIAllocateBuffer function, to be used to allocate memory.

  • lpAllocateMore
    [in] Pointer to the MAPIAllocateMore function, to be used to allocate additional memory.

  • lpFreeBuffer
    [in] Pointer to the MAPIFreeBuffer function, to be used to free memory.

  • lpvReserved
    [in] Reserved; must be zero.

  • lppPropData
    [out] Pointer to a pointer to the returned property data object.

Return Value

  • S_OK
    The call succeeded and has returned the expected value or values.

  • MAPI_E_INTERFACE_NOT_SUPPORTED
    The requested interface is not supported for this object.

Remarks

The lpAllocateBuffer, lpAllocateMore, and lpFreeBuffer input parameters point to the MAPIAllocateBuffer, MAPIAllocateMore, and MAPIFreeBuffer functions, respectively. A client application calling CreateIProp passes in pointers to the MAPI functions just named; a service provider passes the pointers to these functions it received in its initialization call or retrieved with a call to the IMAPISupport::GetMemAllocRoutines method.
