[Bluez-devel] Retrieving an Array of Strings, that is attached to a G_HASH_TABLE variant

In Bluez, certain messages return a GHashTable of type (G_TYPE_STRING, G_TYPE_VALUE), so the key is a String, and the value is a Variant.  Many of the values returned are boolean, integer, and other simple types; others are a boxed Object Path.  These I can handle.

However, in a couple of cases, the value returned is an array of pointers to strings (G_TYPE_STRV).

To retrieve the strings, I am trying something like the following:

(GStrv) gPropValue = (GStrv) g_hash_table_lookup(propTable, "Strings"); // Assume that the "key" is "Strings"
if (gPropValue) {
  while (*gPropValue) {
    cout << *gPropValue << endl;
    ++gPropValue;
  }
}

I do get a properly terminated list of pointers, but each pointer points to a null string. ('\0')

I have not yet added debug statements to syslog (my next step) into the system level code, but why are the strings not filled in?  What else am I missing?  Any suggestions?
