gras_msg_send on the sender side, and \ref gras_msg_wait on the receiver side.
\ref gras_msg_send expects 3 arguments: the socket on which to send the
-message, the message type, and a pointer to the actual content of the
-message. The simplest way to retrive a message type from its name is to use
-\ref gras_msgtype_by_name. Since we don't have any payload, this becomes:
+message, the message type (described by its name), and a pointer to the actual content of the
+message. Since we don't have any payload, this becomes:
\dontinclude 02-simple.c
\skip msg_send
