[Bluez-devel] sdp_record_register()

[<ari.paavilainen@pp.inet.fi>]

Hi,

I found following thing in sdp_record_register():
The comment in source code tells that the function returns non-null pointer on 
success and -1 on failure. I have investigated the code and found out that the 
function returns only 0 or -1:
There are two return commands in the function: return -1; and return status; 
and for status: status=-1; and status = sdp_send_req_w4_rsp(...); In 
sdp_send_req_w4_rsp() there is three times return -1; and one return 0;
So, is the return value zero success here?

But the main problem here is that I can't register a bluetooth service with 
the sdp_record_register() ('sdptool browse local' doesn't list it). I have used 
following code (by Albert Huang):
All function calls succeed.

sdp_session_t *register_service()
{
    int ret;
    uint32_t service_uuid_int[] = { 0, 0, 0, 0xABCD };
    uint8_t rfcomm_channel = 11;
    const char *service_name = "Name";
    const char *service_dsc = "Description";
    const char *service_prov = "Service provider";

    uuid_t root_uuid, l2cap_uuid, rfcomm_uuid, svc_uuid;
    sdp_list_t *l2cap_list = 0, 
               *rfcomm_list = 0,
               *root_list = 0,
               *proto_list = 0, 
               *access_proto_list = 0;
    sdp_data_t *channel = 0, *psm = 0;

    sdp_record_t *record = sdp_record_alloc();

    // set the general service ID
    sdp_uuid128_create( &svc_uuid, &service_uuid_int );
    sdp_set_service_id(record, svc_uuid );

    // make the service record publicly browsable
    sdp_uuid16_create(&root_uuid, PUBLIC_BROWSE_GROUP); 
    root_list = sdp_list_append(0, &root_uuid);
    sdp_set_browse_groups(record, root_list );

    // set l2cap information
    sdp_uuid16_create(&l2cap_uuid, L2CAP_UUID);
    l2cap_list = sdp_list_append( 0, &l2cap_uuid );
    proto_list = sdp_list_append( 0, l2cap_list );

    // set rfcomm information
    sdp_uuid16_create(&rfcomm_uuid, RFCOMM_UUID); 
    channel = sdp_data_alloc(SDP_UINT8, &rfcomm_channel);
    rfcomm_list = sdp_list_append( 0, &rfcomm_uuid );
    sdp_list_append( rfcomm_list, channel ); 
    sdp_list_append( proto_list, rfcomm_list );

    // attach protocol information to service record
    access_proto_list = sdp_list_append( 0, proto_list );
    sdp_set_access_protos( record, access_proto_list );

    // set the name, provider, and description
    sdp_set_info_attr(record, service_name, service_prov, service_dsc);

    int err = 0;
    sdp_session_t *session = 0;
    // connect to the local SDP server, register the service record, and 
    // disconnect
    session = sdp_connect( BDADDR_ANY, BDADDR_LOCAL, SDP_RETRY_IF_BUSY );
    err = sdp_record_register(session, record, 0);

    // cleanup
    sdp_data_free( channel );
    sdp_list_free( l2cap_list, 0 );
    sdp_list_free( rfcomm_list, 0 );
    sdp_list_free( root_list, 0 );
    sdp_list_free( access_proto_list, 0 );

    return session;
}
