November 12, 2021 betterC and exceptions | ||||

 | What does it take to get some kind of exceptions in betterC? I would think that it would be sufficient to either limit the size of an exception and provide a fixed size buffer in thread-local-storage (256 bytes). Yes, that means giving up throwing "strings" and retaining old exceptions, but I think that is acceptable for system level programming. | |||

This? https://github.com/hmmdyl/LWDR Hm, looks like they add a lot of stuff, but some of it seems to be opt-in. Their plan says they have a working implementation for GDC, but not LDC: https://github.com/hmmdyl/SAoC2021/blob/main/plan.md Ok, let's see what they come up with. The ideal would be to reuse whatever C++ does. | |||

 Posted in reply to Ola Fosheim Grøstad | betterC doesn't need exception why do you want that? use error codes if that's not enough, let's think about something better than exception | |||

I believe C++ uses reference counting.

Each compiler does its own way, and on Visual C++'s case it takes advantage that Windows supports exceptions at the OS level.
