GstMemoryMapInfo

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.Buffer.unmap or gst.memory.Memory.unmap.

See also #GstBufferMapInfo.
