+ * TRACE CATEGORIES
+ */
+
+/*
+ * The trace messages of the OpenSSL libraries are organized into different
+ * categories. For every trace category, the application can register a separate
+ * tracer callback. When a callback is registered, a so called trace channel is
+ * created for this category. This channel consists essentially of an internal
+ * BIO which sends all trace output it receives to the registered application
+ * callback.
+ *
+ * The ALL category can be used as a fallback category to register a single
+ * channel which receives the output from all categories. However, if the
+ * application intends to print the trace channel name in the line prefix,
+ * it is better to register channels for all categories separately.
+ * (This is how the openssl application does it.)

+
+/*
+ * OSSL_TRACE_BEGIN, OSSL_TRACE_END - Define a Trace Group
+ *
+ * These two macros can be used to create a block which is executed only
+ * if the corresponding trace category is enabled. Inside this block, a
+ * local variable named |trc_out| is defined, which points to the channel
+ * associated with the given trace category.
+ *
+ * Usage: (using 'TLS' as an example category)
+ *
+ *     OSSL_TRACE_BEGIN(TLS) {
+ *
+ *         BIO_fprintf(trc_out, ... );
+ *
+ *     } OSSL_TRACE_END(TLS);
+ *
+ *
+ * This expands to the following code
+ *
+ *     do {
+ *         BIO *trc_out = OSSL_trace_begin(OSSL_TRACE_CATEGORY_TLS);
+ *         if (trc_out != NULL) {
+ *             ...
+ *             BIO_fprintf(trc_out, ...);
+ *         }
+ *         OSSL_trace_end(OSSL_TRACE_CATEGORY_TLS, trc_out);
+ *     } while (0);
+ *
+ * The use of the inner '{...}' group and the trailing ';' is enforced
+ * by the definition of the macros in order to make the code look as much
+ * like C code as possible.
+ *
+ * Before returning from inside the trace block, it is necessary to
+ * call OSSL_TRACE_CANCEL(category).
