  71 @brief  Babeltrace's boolean type.
  72
  73 Use only the #BT_FALSE and #BT_TRUE definitions for #bt_bool parameters.
  74 It is guaranteed that the library functions which return a #bt_bool
  75 value return either #BT_FALSE or #BT_TRUE.
  76
  77 You can always test the truthness of a #bt_bool value directly, without
  78 comparing it to #BT_TRUE directly:
  79
  80 @code
  81 bt_bool ret = bt_some_function(...);
  82
  83 if (ret) {
  84         // ret is true
  85 }
