[Bluez-devel] Cleaning up after sdp_get_access_protos()

["Daryl Van Vorst" <daryl@wideray.com>]

Hi,

This stuff hurts my brain, so I was hoping someone (Marcel? ;) could =
verify
my logic.

I'm mentioning this mostly because the utils code gets used as example =
code.

In this snippet from sdptool.c, proto is cleaned up with
sdp_list_free(proto, (sdp_free_func_t)sdp_data_free);

        if (sdp_get_access_protos(rec, &proto) =3D=3D 0) {
                printf("Protocol Descriptor List:\n");
                sdp_list_foreach(proto, print_access_protos, 0);
                sdp_list_free(proto, (sdp_free_func_t)sdp_data_free);
        }

I think the cleanup should be:

    sdp_list_foreach(proto,(sdp_list_func_t)sdp_list_free,0);
    sdp_list_free(proto,0);

Looking at sdp.c source (in libs), sdp_get_access_protos() returns a =
list of
lists of data sequences. The data sequences themselves shouldn't be =
freed at
this point because they weren't allocated by sdp_get_access_protos() =
(thus
the ,0 in the sdp_list_foreach call). But the list of lists is allocated
inside sdp_get_access_protos().
