Get the interface with IID i_strIID exposed from i_pObj.
- Template Parameters
-
| Provider | Type exposing the |
| VoidType | Where the interface type identified by i_strIID gets statically casted to |
- Precondition
true == std::is_void<VoidType>
- Parameters
-
| [in] | i_pObj | Pointer to object of type Provider exposing the requested interface. |
| [in] | i_strIID | The queried IID which identifies the interface type to retrieve. |
| [out] | o_pInterface | Pointer to reference of type (const) void the interface is cast to. nullptr if IID matches one of the exposed interfaces. |
- Returns
- Standard error code.
- Return values
-
| ERR_NOERROR | Everything went fine (o_pInterface != nullptr) |
| ERR_NO_INTERFACE | i_pObj doesn't expose the requested Interface (o_pInterface == nullptr) |
