it would be nice add to queue.h xQUEUE structure definition or more function. My need now is using pxQueue->uxMessagesWaiting from ISR…

The data type is deliberately hidden to prevent direct access.  This enables the queue implementation to change without effecting application code.

For your particular needs you could add a simple get function (without the critical sections so it can be used from the ISR), or move the queue definition to the header file.

yes, I’ve done:
unsigned portBASE_TYPE uxQueueMessagesWaitingFromISR( xQueueHandle pxQueue )    // JU
{
    return pxQueue->uxMessagesWaiting;
}

but it would be nice to be compatible with original the OS…
