From 4a4f41ed642cd5d9f4056b12d86bbf80e8da983a Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Wed, 23 Sep 2020 16:47:58 +0200 Subject: rtems: Add rtems_message_queue_construct() In contrast to message queues created by rtems_message_queue_create(), the message queues constructed by this directive use a user-provided message buffer storage area. Add RTEMS_MESSAGE_QUEUE_BUFFER() to define a message buffer type for message buffer storage areas.
