/*
* The six macros below are logging statements which are specialized
* for the Babeltrace library.
* 3. Optional: `+` to print extended fields. This depends on the
* provided format specifier.
*
- * 4. Format specifier.
+ * 4. Objet category: `w` for CTF writer objects, `_` for common
+ * objects, or nothing for default objects (includes CTF IR).
+ *
+ * 5. Format specifier (see below).
*
* The available format specifiers are:
*
- * `r`:
- * Reference count information. The parameter is any Babeltrace
- * object.
+ * Default category:
+ * `r`:
+ * Reference count information. The parameter is any Babeltrace
+ * object.

+ * Conversion specifier examples:
+ *
+ * %!f
+ * %![my-event-]+e
+ * %!_t
+ * %![ctf-writer-ec-]wE
+ * %!+_F
*
* The string `, ` is printed between individual fields, but not after
* the last one. Therefore you must put this separator in the format
* It is safe to pass NULL as any Babeltrace object parameter: the
* macros only print its null address.
