MarkJG (May 03 2021 at 13:26): MarkJG (May 03 2021 at 13:26):How do I get a exported function by name? Rust's got get_typed_func, but I can't find anything similar in the C API. Most of the C examples get externs funcs by index.
Alex Crichton (May 03 2021 at 14:09):Currently we don't have an equivalent in the C API
Alex Crichton (May 03 2021 at 14:09):one of the main reasons is that we're not ready to commit yet to a stable ABI for functions, so there's no great way to expose this in C right now (that we know of)
MarkJG (May 03 2021 at 16:20):Thanks for the response, it's quite alright. I've managed to work around it with wasm_module_exports, just by mapping the externtype names to extern indices. It's a glued on solution but seems to work well enough for now.
Yury Delendik (May 03 2021 at 17:02):It is actually not a workaround. That's how you need to do it.
MarkJG (May 03 2021 at 18:58):Hi Yury. What do you mean?
MarkJG (May 03 2021 at 18:59):I'm not interested in the function's signature if that's what you meant.
Yury Delendik (May 03 2021 at 19:11):In most of the cases binding by name is inefficient or tricky at runtime. The C api "suggest" that all inefficient stuff will be accomplish during initial linking and indexes are used instead of names later during runtime.
MarkJG (May 03 2021 at 19:33):That's what I'm doing. I'm building up a map of name's to extern indices after I load the module binary.
