= Library Applets =
This section documents library applet launching.
Before starting the applet, [[#IStorage]]s are created and written, then passed to [[#ILibraryAppletAccessor]] PushInData. The [[#IStorage]] session is closed afterwards. The first [[#IStorage]] is [[#CommonArguments]], followed by any applet-specific [[#IStorage]]s.
Once the applet finishes running successfully, [[#ILibraryAppletAccessor]] PopOutData can be used to get the applet-specific [[#IStorage]] containing the applet output data.
== CommonArguments ==
The first [[#IStorage]] passed to applets should contain the common library applet arguments. This is populated by <code>nn::la::CommonArgumentsWriter</code> and has the following format.
This struct is 0x20-bytes.
