Function opencl3::command_queue::enqueue_map_image

pub fn enqueue_map_image(
    command_queue: *mut c_void, 
    image: *mut c_void, 
    blocking_map: u32, 
    map_flags: u64, 
    origin: *const usize, 
    region: *const usize, 
    image_row_pitch: *mut usize, 
    image_slice_pitch: *mut usize, 
    image_ptr: &mut *mut c_void, 
    num_events_in_wait_list: u32, 
    event_wait_list: *const *mut c_void
) -> Result<*mut c_void, i32>

Note: returns event NOT pointer for consistency with other enqueue functions.
The image pointer is returned in the image_ptr mutable reference.
