xQueueContains ?

Hi How do I determine if a queue contains an item?

xQueueContains ?

You can only peek the first item in a queue there is no function to search a queue.

xQueueContains ?

I just got dumped in this project, so my experience with FreeRTOS is limited. Is it better to use my own queue code or attempt to add a xQueueContains to the existing code?
