wasm export arguments #16

Open konsumer opened 11 months ago

konsumer commented 11 months ago

How do I provide an argument to a function? I looked around in code, and didn't really see anything.

For example, I want to expose malloc from my wasm, it has 1 arg (size):

// How to insert an arg here?
web49_interp_data_t* data = web49_interp_block_run(interp, &interp->funcs[mallocID]);
uint32_t wptr = data->i32_u;
