/*
- * The pr routine historically arranged for nonbuffered i/o
- * because stdio didn't used to automatically flush stdout before
- * it read something from stdin. Now pr() prepends an "output id"
- * in front of each line of text, informing the user interface
- * what sort of item it is seeing; prompt, noecho prompt,
- * more input data, etc.
+ * Player output is fully buffered. It can block only if the
+ * receiving player is the current player and his last command doesn't
+ * have the C_MOD flag. Output to another player must not block
+ * because that player could be gone when the printing thread wakes
+ * up, and the code isn't prepared for that. Output within C_MOD
+ * command never blocks, so that such commands can print freely
+ * without yielding the processor.
+ *
+ * Each line of output starts with an identification character
+ * encoding the output id, followed by space. Ids less than 10 are
+ * encoded as decimal digits, and larger ids as lower case letters,
+ * starting with 'a'. Symbolic names for ids are defined in proto.h.
