[PATCH 1/2] core: Replace calls to g_queue_free_full function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The function g_queue_free_full is available only from GLib 2.32.
If BlueZ has to build against GLib 2.28, as stated in the configure.ac,
this patch replaces the calls to g_queue_free_full in the "core" BlueZ module
with its body, taken from the sources of GLib 2.32.
