Function streamParseIntervalIDOrReply

app/redis-6.2.6/src/t_stream.c:1747–1762

Helper for parsing a stream ID that is a range query interval. When the * exclude argument is NULL, streamParseIDOrReply() is called and the interval * is treated as close (inclusive). Otherwise, the exclude argument is set if * the interval is open (the "(" prefix) and streamParseStrictIDOrReply() is * called in that case. */

 * called in that case.
