Message Queues (IPC)
Message Queues
- Either one task or group of tasks can use the queue
- Usually queue is circular. elements are accessed by means of FIFO.
- Printer task is an example
- Initialization before using the function
- provision for multiple queues. each queue will be having an ID
- size of the queue is either user defined or predefined by the scheduler
- There may be a need for error handler, when a queue is full.
