If you want to send the pointer to the callback, you need to get the content of the pointer yourself (i.e. don't even use embind for your struct). Bad idea IMO.

WebAug 13, 2024 · In Emscripten, typed_memory_view returns a JavaScript Uint8Array backed by the WebAssembly (Wasm) memory buffer, with byteOffset and byteLength set to the given pointer and length. The main point is that this is a TypedArray view into a WebAssembly memory buffer, rather than a JavaScript-owned copy of the data. Weballow_subclass adds a special implement method to Interface so invoke can be implemented in JavaScript. var x = { invoke: function(str) { console.log('invoking with: ' + str); } }; var interfaceObject = Module.Interface.implement(x); Now interfaceObject can be passed to any function that takes an Interface pointer. proud mary on guitarWebClone via HTTPS Clone with Git or checkout with SVN using the repository’s web address. respected parents

Not only is this a natural choice for the bindings, but because it is low-level it is relatively easy to optimize.
