67 @brief Babeltrace's boolean type.
68
69 Use only the #BT_FALSE and #BT_TRUE definitions for #bt_bool parameters.
70 It is guaranteed that the library functions which return a #bt_bool
71 value return either #BT_FALSE or #BT_TRUE.
72
73 You can always test the truthness of a #bt_bool value directly, without
74 comparing it to #BT_TRUE directly:
75
76 @code
77 bt_bool ret = bt_some_function(...);
78
79 if (ret) {
80 // ret is true
81 }
