What happened to "LINECMP_GetClass" inside IDiffView?

I have some code that I am trying to build and it uses the function

through the

interface.

I get an undefined reference to this function which seems to make sense since I cannot see it in my SDK at all.

...

Maybe I will have a look through the old SDKs.

Possibly has been removed. The XYZ_GetClass() functions, originally used in ReAction to obtain the class pointer, are now obsolete because you're expected to open BOOPSI classes via IIntuition->OpenClass(), which gives you the class pointer as well as the class library base.

Right, so I guess I will have to build with an older SDK.

Or open the classes with OpenClass() instead of OpenLibrary().

I cannot actually find this function even as far back as 53.30.

Is it external to the SDK? I also cannot find any Reaction sources on AmiNet/OS4Depot.

Are you referring to OpenClass()/CloseClass() functions? If so they've been in intuition.library since the AmigaOS 4.0 pre-releases according to the autodoc.

I am referring to an application that literally:

and uses it in the way described in the only entry for "LINECMP_GetClass()" in the SDK.

For this to work the symbol must exist somewhere or be redefined to something else. When I search in the SDK, entire, for "LINECMP_GetClass", the only thing I see is a match to a documentation file and some example files. Hence, I receive an undefined reference.

I assume there is some code like:


If so just replace it with:
