\brief Invokes this function with the params given, returning the results asynchronously.

This function is the same as wasmtime_func_call except that it is asynchronous. This is only compatible with stores associated with an asynchronous config.

The result is a future that is owned by the caller and must be deleted via #wasmtime_call_future_delete.

The args and results pointers may be NULL if the corresponding length is zero. The trap_ret and error_ret pointers may not be NULL.

Does not take ownership of #wasmtime_val_t arguments or #wasmtime_val_t results, and all parameters to this function must be kept alive and not modified until the returned #wasmtime_call_future_t is deleted. This includes the context and store parameters. Only a single future can be alive for a given store at a single time (meaning only call this function after the previous call's future was deleted).

See the header documentation for for more information.
