Specify a callback for trace events occurring in krb5 operations performed within context . fn will be invoked with context as the first argument, cb_data as the last argument, and a pointer to a krb5_trace_info as the second argument. If the trace callback is reset via this function or context is destroyed, fn will be invoked with a NULL second argument so it can clean up cb_data . Supply a NULL value for fn to disable trace callbacks within context .
