@Generated("org.javagi.JavaGI")
public class MemoryMapInfo
extends MapInfo

Alias for GstMapInfo to be used with g_auto():

void my_func(GstMemory *mem)
{
  g_auto(GstMemoryMapInfo) map = GST_MAP_INFO_INIT;
  if (!gst_memory_map(mem, &map, GST_MAP_READWRITE))
    return;
  ...
  // No need to call gst_memory_unmap()
}

GstMapInfo cannot be used with g_auto() because it is ambiguous whether it needs to be unmapped using gst_buffer_unmap() or gst_memory_unmap().

See also GstBufferMapInfo.
