Mikko Mononen @mikkomononen.bsky.social · 14/05/2025Does anyone have a good API in C for getting dynamic array of results back? Sometimes it is possible to do a "double call", where you pass in array + max size (which both can be null), and it always returns the actual number of items. 260
Mikko Mononen @mikkomononen.bsky.social · 14/05/2025I have a couple of cases in my API that does a bit more work so I'd like to avoid running things twice. One option that I found working ok is this: struct ResultArray { type* items; int count; int cap; GrowFunc* grow; FreeFunc* free; void* user_ptr; } 100
Séb @sebdegraff.bsky.social · 14/05/2025I don’t know if it fits your use case but recently I’ve started using a temp allocator for such results, reset every frame. If you want to hold to the data for longer, you copy it wherever you need. 95% of the time you don’t need to, and it makes for a simple api 100
