8 | * Write a packetized stream, where each line is preceded by |
9 | * its length (including the header) as a 4-byte hex number. | |
10 | * A length of 'zero' means end of stream (and a length of 1-3 | |
11 | * would be an error). | |
12 | * | |
13 | * This is all pretty stupid, but we use this packetized line | |
14 | * format to make a streaming format possible without ever | |
15 | * over-running the read buffers. That way we'll never read | |
16 | * into what might be the pack data (which should go to another | |
17 | * process entirely). | |
18 | * | |
19 | * The writing side could use stdio, but since the reading | |
20 | * side can't, we stay with pure read/write interfaces. | |
