nn::fs::IsSdmcInserted Functionbool IsSdmcInserted();
None.
Returns a value indicating whether an SD Card has been inserted.
Because this function represents a high load, be sure to use nn::os::LightEvent, registered using the nn::fs::RegisterSdmcInsertedEvent or nn::fs::RegisterSdmcEjectedEvent function, when waiting for an SD Memory Card insertion or ejection event.
