engiGetInstanceAttrTypeBN

Combines sdaiGetAttrDefinition and engiGetInstanceAttrType. Technically engiGetInstanceAttrTypeBN will transform into the following call

    engiGetInstanceAttrType(
            instance,
            sdaiGetAttrDefinition(
                    sdaiGetInstanceType(
                            instance
                        ),
                    attributeName
                )
        );

Syntax

public const string ifcenginedll = @"ifcengine.dll";

[DllImport(IFCEngineDLL, EntryPoint = "engiGetInstanceAttrTypeBN")]
public static extern Int32 engiGetInstanceAttrTypeBN(int_t instance, string attributeName);

[DllImport(IFCEngineDLL, EntryPoint = "engiGetInstanceAttrTypeBN")]
public static extern Int32 engiGetInstanceAttrTypeBN(int_t instance, byte[] attributeName);
