- * \brief guts of oscilloscope trigger and buffer module
- *
- * This module processes sets of samples provided the \p
- * process_sample method. When appropriate given the updateRate,
- * sampleRate and trigger conditions, process_sample will
- * periodically write output records of captured data to
- * output_fd. For each trigger event, nchannels records will be
- * written. Each record consists of get_samples_per_output_record
- * binary floats. The trigger instant occurs at the 1/2 way point
- * in the buffer. Thus, output records consist of 50% pre-trigger
- * data and 50% post-trigger data.
