/**
@brief	Babeltrace's boolean type.

Use only the #BT_FALSE and #BT_TRUE definitions for #bt_bool parameters.
It is guaranteed that the library functions which return a #bt_bool
value return either #BT_FALSE or #BT_TRUE.

You can always test the truthness of a #bt_bool value directly, without
comparing it to #BT_TRUE directly:

@code
bt_bool ret = bt_some_function(...);

if (ret) {
	// ret is true
}
