HRESULT HrGetOneProp(
LPMAPIPROP pmp,
ULONG ulPropTag,
LPSPropValue FAR * ppprop
);
Parameters
pmp
[in] Pointer to the IMAPIProp interface from which the property value is to be retrieved.
ulPropTag
[in] Property tag of the property to be retrieved.
ppprop
[out] Pointer to a pointer to the returned SPropValue structure defining the retrieved property value.
Return value
MAPI_E_NOT_FOUND
The requested property is not available from the specified interface.
Remarks
Unlike the IMAPIProp::GetProps method, the HrGetOneProp function never returns any warning. Because it retrieves only one property, it simply either succeeds or fails. For retrieving multiple properties, GetProps is faster.
You can set or change a single property with the HrSetOneProp function.
