34 get more finegrained trace information. This callback will be wrapped
37 For the tracing code, both trace channel types are indistinguishable.
38 These are called a I<simple trace channel> and a I<callback trace channel>,
44 can be used for producing free-text trace output.
48 OSSL_trace_set_channel() is used to enable the given trace C<category>
49 by attaching the B<BIO> I<bio> object as (simple) trace channel.
62 OSSL_trace_set_callback() is used to enable the given trace
66 dedicated BIO object, the so-called I<callback trace channel>.
67 This should be used when it's desirable to do form the trace output to
116 The trace categories are simple numbers available through macros.
