    this function leaks a channel reference



/trunk/funcs/func_groupcount.c

    ast_asprintf() will simplify this

    There are now some constants defined for use as return values from manager actions

    It looks like you have some tabs vs. spaces issues

    I don't really like the idea of a new API that exposes a raw linked list.  I'd rather that the API be internal storage agnostic.  An API call like ast_app_group_callback() would work for me.
    
    If the internal storage were to be converted to astobj2, I would be even happier.  :-)
