Function signatue in wasm64

[tbuchs]

Hi, I try to port my code to wasm64 and have some issues with calling a thread on the main thread. I use the flag -sPROXY_TO_PTHREAD and need some work to be done of the main thread. I used to use emscripten_sync_run_in_main_runtime_thread and it worked perfectly fine. However, now with wasm64 I have the issue, that I always get the error of a wrong function signature.
The function looks like this: void (*ptr)(void*, unsigned char*, int) = &callback_method; - what would be the right EM_FUNC_SIG_ to use then?

I tried EM_FUNC_SIG_VPPI, but as far as I can see, this doesn't exist. Thanks for any help!

Yes, we only added a few EM_FUNC_SIG variants with P in them. This is because we tend to use the new proxying.h API for proxying work these days. If you would like add a more EM_FUNC_SIG variants feel free to send a PR.

Interesting, is there a way to achieve the behavior of emscripten_sync_run_in_main_runtime_thread by using proxying.h?
Otherwise I gladly add a new variant - like always: thanks again for your great support :)

Yes, if you want to switch to the API you would use emscripten_proxy_get_system_queue() to get the system queue and then you can use emscripten_proxy_sync or emscripten_proxy_sync_with_ctx to do the actual proxying.

I will likely take a few more lines of code and since we don't use those type reflecting macros in the new API.. its more straight forward C. However I think there is a C++ API that is more powerful.

Thanks for your help, this works perfectly!
