[LAD] snd_seq_port_info and shared_ptr

-----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?

Thanks for your help!
