 /*
- * Receive a stick-table message.
+ * Receive a stick-table message or pre-parse any other message.
+ * The message's header will be sent into <msg_head> which must be at least
+ * <msg_head_sz> bytes long (at least 7 to store 32-bit variable lengths).
+ * The first two bytes are always read, and the rest is only read if the
+ * first bytes indicate a stick-table message. If the message is a stick-table
+ * message, the varint is decoded and the equivalent number of bytes will be
+ * copied into the trash at trash.area. <totl> is incremented by the number of
+ * bytes read EVEN IN CASE OF INCOMPLETE MESSAGES.
  * Returns 1 if there was no error, if not, returns 0 if not enough data were available,
  * -1 if there was an error updating the appctx state st0 accordingly.
