Function panda_sys::qemu_co_sendv_recvv

pub unsafe extern "C" fn qemu_co_sendv_recvv(
    sockfd: c_int, 
    iov: *mut iovec, 
    iov_cnt: c_uint, 
    offset: size_t, 
    bytes: size_t, 
    do_send: bool
) -> ssize_t

Sends a (part of) iovec down a socket, yielding when the socket is full, or Receives data into a (part of) iovec from a socket, yielding when there is no data in the socket. The same interface as qemu_sendv_recvv(), with added yielding. XXX should mark these as coroutine_fn
