nn::fs::IsSdmcInserted Functionbool IsSdmcInserted();
None.
true if a card is inserted; otherwise, returns false. Returns a value indicating whether an SD Card has been inserted.
Because this function puts a heavy load on the processor, when waiting for an SD Memory Card insertion or removal event, use an nn::os::LightEvent object registered using the nn::fs::RegisterSdmcInsertedEvent or nn::fs::RegisterSdmcEjectedEvent function.
