How to block task forever with a Queue()?

Posted by Nobody/Anonymous on November 8, 2005
Hi all,

I want to block a task forever with xQueueReceive(..., ... , SomethingLikeWAIT_FOREVER).
Only data posted to the Queue should wake up the task. I do not want to change task priority.

Is there a simpler method as checking the uxQueueMessagesWaiting() and when no data received calling the taskYIELD() ?

The normal way to do this is:

while( !xQueueReceive( Queue, buffer, portMAX_DELAY ) );

When the delay exists because something has been received then the while loop will also exit.

This topic has come up before. It was a design decission not to have a WAIT_FOREVER to keep the RAM usage of the compiler to a minimum and the source code as small as possible.
