49 * A writer is modifying the record.
52 * The record and all its data are written. A writer can reopen the
58 * writer cannot reopen the descriptor.
87 * When a writer calls the commit function prb_commit(), record data is
88 * fully stored and is consistent within the ringbuffer. However, a writer can
90 * modify that record. When finished, the writer must again commit the record.
97 * 1) A writer can simultaneously commit and finalize its record by calling
115 * Each data block consists of an ID followed by the writer data. The ID is
