sdaiGetInstanceAttrBN

This function is a specific version of sdaiGetAttrBN(..), where the valueType is sdaiINSTANCE. This call can be usefull in case of specific programming languages that cannot map towards sdaiGetAttrBN(..) directly, this function is useless for languages as C, C++, C#, JAVA, VB.NET, Delphi and similar as they are able to map sdaiGetAttrBN(..) directly. Technically sdaiGetInstanceAttrBN will transform into the following call

    SdaiInstance    inst = 0;
    sdaiGetAttr(
            instance,
            sdaiGetAttrDefinition(
                    sdaiGetInstanceType(
                            instance
                        ),
                    attributeName
                ),
            sdaiINSTANCE,
            &inst
        );
    return  inst;
