Enumeration Type Documentation

Message_queue_MP_Remote_operations

enum Message_queue_MP_Remote_operations

The following enumerated type defines the list of remote message queue operations.

Function Documentation

_Message_queue_Core_message_queue_mp_support()

void _Message_queue_Core_message_queue_mp_support	(	Thread_Control *	the_thread,
		rtems_id	id
	)

Message_queue_Core_message_queue_mp_support.

Input parameters: the_thread - the remote thread the message was submitted to id - id of the message queue

Output parameters: NONE

_Message_queue_MP_Send_object_was_deleted()

void _Message_queue_MP_Send_object_was_deleted	(	Thread_Control *	the_proxy,
		Objects_Id	mp_id
	)

_Message_queue_MP_Send_object_was_deleted

This routine is invoked indirectly by the thread queue when a proxy has been removed from the thread queue and the remote node must be informed of this.

_Message_queue_MP_Send_process_packet()

void _Message_queue_MP_Send_process_packet	(	Message_queue_MP_Remote_operations	operation,
		Objects_Id	message_queue_id,
		rtems_name	name,
		Objects_Id	proxy_id
	)

_Message_queue_MP_Send_process_packet

This routine performs a remote procedure call so that a process operation can be performed on another node.
