That's fine I guess, but is there any issue with returning the refcounts? It appears that we use them sporadically, like `wined3d_stateblock_decref` return value is used to print an error in `d3d_device7_DeleteStateBlock`. I'd rather not do the work unless there's some reason to. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1755#note_19631
As might have been guessed this was my idea. It was brought on during the long types conversion; I figured there wasn't really reason for the refcounting functions to return any value, since a well-behaved program should never care, and a few ERR messages wasn't really worth it. I don't mind dropping these patches, though. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1755#note_19638
I don't really mind including these either, just don't see the upside - I don't think returning the values costs anything in terms of runtime? On the other hand I could imagine using them for debugging reference count underflows. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1755#note_19670
Yeah, if it's not clearly an improvement it's probably better to close it rather than spend time discussing it. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1755#note_19802
