-/*
- * The six macros below are logging statements which are specialized
- * for the Babeltrace library.
- *
- * `_fmt` is a typical printf()-style format string, with the following
- * limitations:
- *
- * * The `*` width specifier is not accepted.
- * * The `*` precision specifier is not accepted.
- * * The `j` and `t` length modifiers are not accepted.
- * * The `n` format specifier is not accepted.
- * * The format specifiers defined in <inttypes.h> are not accepted
- * except for `PRId64`, `PRIu64`, `PRIx64`, `PRIX64`, `PRIo64`, and
- * `PRIi64`.
- *
- * The Babeltrace extension conversion specifier is accepted. Its syntax
- * is either `%!u` to format a UUID (`bt_uuid` type) or:
- *
- * 1. Introductory `%!` sequence.
- *
- * 2. Optional: `[` followed by a custom prefix for the printed fields
- * of this specifier, followed by `]`. The standard form is to end
- * this prefix with `-` so that, for example, with the prefix
- * `prefix-`, the complete field name is `prefix-addr`.
- *
- * 3. Optional: `+` to print extended fields. This depends on the
- * provided format specifier.
- *
- * 4. Format specifier (see below).
- *
- * The available format specifiers are:
- *
- * `F`:
- * Trace IR field class. The parameter type is
- * `struct bt_field_class *`.
- *
- * `f`:
- * Trace IR field. The parameter type is `struct bt_field *`.
- *
- * `P`:
- * Field path. The parameter type is `struct bt_field_path *`.
- *
- * `E`:
- * Trace IR event class. The parameter type is
- * `struct bt_event_class *`.
- *
- * `e`:
- * Trace IR event. The parameter type is `struct bt_event *`.
- *
- * `S`:
- * Trace IR stream class. The parameter type is
- * `struct bt_stream_class *`.
- *
- * `s`:
- * Trace IR stream. The parameter type is `struct bt_stream *`.
- *
- * `a`:
- * Packet. The parameter type is `struct bt_packet *`.
- *
- * `T`:
- * Trace IR trace class. The parameter type is `struct bt_trace_class *`.
- *
- * `t`:
- * Trace IR trace. The parameter type is `struct bt_trace *`.
- *
- * `K`:
- * Clock class. The parameter type is `struct bt_clock_class *`.
- *
- * `k`:
- * Clock snapshot. The parameter type is `struct bt_clock_snapshot *`.
- *
- * `v`:
- * Value. The parameter type is `struct bt_value *`.
- *
- * `n`:
- * Message. The parameter type is `struct bt_message *`.
- *
- * `i`:
- * Message iterator. The parameter type is
- * `struct bt_message_iterator *`.
- *
- * `C`:
- * Component class. The parameter type is
- * `struct bt_component_class *`.
- *
- * `c`:
- * Component. The parameter type is `struct bt_component *`.
- *
- * `p`:
- * Port. The parameter type is `struct bt_port *`.
- *
- * `x`:
- * Connection. The parameter type is `struct bt_connection *`.
- *
- * `g`:
- * Graph. The parameter type is `struct bt_graph *`.
- *
- * `l`:
- * Plugin. The parameter type is `const struct bt_plugin *`.
- *
- * `o`:
- * Object pool. The parameter type is `struct bt_object_pool *`.
- *
- * `O`:
- * Object. The parameter type is `struct bt_object *`.
- *
- * Conversion specifier examples:
- *
- * %!f
- * %![my-event-]+e
- * %!t
- * %!+F
- *
- * The string `, ` is printed between individual fields, but not after
- * the last one. Therefore you must put this separator in the format
- * string between two conversion specifiers, e.g.:
- *
- * BT_LIB_LOGW("Message: count=%u, %!E, %!+K", count, event_class,
- * clock_class);
- *
- * Example with a custom prefix:
- *
- * BT_LIB_LOGI("Some message: %![ec-a-]e, %![ec-b-]+e", ec_a, ec_b);
- *
- * It is safe to pass NULL as any Babeltrace object parameter: the
- * macros only print its null address.
