Function wasmer_vm::wasmer_call_trampoline

pub unsafe fn wasmer_call_trampoline(
    callee_env: VMFunctionEnvironment,
    trampoline: VMTrampoline,
    callee: *const VMFunctionBody,
    values_vec: *mut u8
) -> Result<(), Trap>

Call the VM function pointed to by callee.

• callee_env - the function environment
• trampoline - the jit-generated trampoline whose ABI takes 3 values, the callee funcenv, the callee argument below, and then the values_vec argument.
• callee - the 2nd argument to the trampoline function
• values_vec - points to a buffer which holds the incoming arguments, and to which the outgoing return values will be written.

Prefer invoking this via Instance::invoke_trampoline.

Safety

Wildly unsafe because it calls raw function pointers and reads/writes raw function pointers.
