Hi Netra,

Wow that is very old version of MQX. Please note latest download (http://www.freescale.com/mqx) is MQX4.0.2.GA.

In your MQX3.5\docs\mqx\MQXUG.pdf please review information on the following:

2.6.7 Task Queues

In addition to providing a scheduling mechanism, task queues provide a simple and efficient way to

synchronize tasks. You can suspend tasks in the task queue and remove them from the task queue.

Regards,

David

for example, set an event or semaphore. the task would poll the event/semaphore in a while(1) loop and call _task_block() in response to it. alternatively you can use task queue to suspend/resume tasks (_taskq_suspend_task(), _taskq_resume()).
