-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 As I'm new to smart pointers and memory management in C++ I have a short question on this topic. I'm now using the following code to traverse the devices and their ports:        snd_seq_client_info_t *clientInfo = 0;        snd_seq_port_info_t *portInfo = 0;        snd_seq_client_info_malloc(&clientInfo);        snd_seq_port_info_malloc(&portInfo);        shared_ptr<snd_seq_client_info_t> clientInfoMemoryHandler(clientInfo, snd_seq_client_info_free);        shared_ptr<snd_seq_port_info_t> portInfoMemoryHandler(portInfo, snd_seq_port_info_free);        .        .        . snd_seq_port_info_set_client( portInfo, snd_seq_client_info_get_client(clientInfo ) ); snd_seq_port_info_set_port( portInfo, -1 ); while ( snd_seq_query_next_port( seq, portInfo ) >= 0 ) {        string portName = snd_seq_port_info_get_name( portInfo );        unsigned int capability = snd_seq_port_info_get_capability( portInfo );        .        .        . Well the cleanUp methods are called at block-leaving. I'm only a bit curious because after giving portInfo and clientInfo to the shared_ptr for cleanup management I have to use them for all the alsa queries. But since I'm not using malloc and free in these queries everything is ok, isn't it?
