Library wrapping question, simple vs redirected

[Javier97sm]

Hello, I am trying to wrap a new library (libjack) so I've been reading the following guide (https://box86.org/2024/02/how-to-create-a-wrapping/) and also taking a look at other wrappings like pulseaudio.

I don't understand when I have to add simple functions with the GO() macro or use GOM(). I see it clear with variadic functions but not very clear for redirected functions. For example, this pulseaudio functions:

GO(pa_threaded_mainloop_accept, vFp)
GOM(pa_threaded_mainloop_free, vFEp)

When you take a look at the pulseaudio source code, this is the functions signature:

void pa_threaded_mainloop_accept(pa_threaded_mainloop m);
void pa_threaded_mainloop_free(pa_threaded_mainloop m);

Both have the same signature, where its argument 'pa_threaded_mainloop' is a pointer to a pretty big struct. But one has its simple and the other redirected. Can someone help me understand the reasoning behind this?

Thanks in advance!

For this particular example, it's because on pa_thread_mainloop_free, box64 needs to do some cleanup at this function, so it has been made GOM while technicaly GO would be enough.

I let @rajdakin also comment there.
