Function ocl_core::enqueue_map_image [] [src]

    command_queue: &CommandQueue,
    image: M,
    block: bool,
    map_flags: MapFlags,
    origin: [usize; 3],

[UNTESTED] Enqueues a command to map a region of the image object given by image into the host address space and returns a pointer to this mapped region.

Safety

Caller must ensure that the returned pointer is not used until the map is complete. Use new_event to monitor it. [TEMPORARY] It also must be ensured that memory referred to by the returned pointer is not dropped, reused, or otherwise interfered with until enqueue_unmap_mem_object is called.

TODO: Return a new wrapped type representing the newly mapped memory.
