xQueueEmpty() ?

Posted by ulmus on January 12, 2012
There is method or function to empty a queue or i can only do it with receive loop?
I cant see any empty method in API.

There is a new xQueueReset() macro, but it is not released yet. If you want to use it then you need queue.c and queue.h from the SVN repository. xQueueReset() in queue.h calls xQueueGenericReset() in queue.c (you should use the macro, not the function).
