According to dbus documentation, dbus_message_iter_append_basic() expects a "const char**" if type is string and a simple pointer for other types. Since we a iterating an array, the value passed is already a pointer. --- src/dbus.c | 20 ++++++++++++++++++-- 1 files changed, 18 insertions(+), 2 deletions(-) diff --git a/src/dbus.c b/src/dbus.c index c24615f..b719217 100644 --- a/src/dbus.c +++ b/src/dbus.c @@ -139,8 +139,24 @@ static void append_dict_variant(DBusMessageIter *iter, int type, void *val) dbus_message_iter_append_basic(&entry, DBUS_TYPE_STRING, &(val_array[i + 0])); - dbus_message_iter_append_basic(&entry, type, - &(val_array[i + 1])); + + /* + * D-Bus expects a char** or uint8* depending on the type + * given.
