)
inlinestaticprivate

Get the interface with IID i_strIID exposed from i_pObj.

Template Parameters
ProviderType exposing the ...Interfaces.
VoidTypeWhere the interface type identified by i_strIID gets statically casted to
Precondition
true == std::is_void<VoidType>
Parameters
[in]i_pObjPointer to object of type Provider exposing the requested interface.
[in]i_strIIDThe queried IID which identifies the interface type to retrieve.
[out]o_pInterfacePointer 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_NOERROREverything went fine (o_pInterface != nullptr)
ERR_NO_INTERFACEi_pObj doesn't expose the requested Interface (o_pInterface == nullptr)
