I have a typical wait_ms function that just waits until a ms counter that is updated on every Systick gets to a value and I thought about doing vTaskDelay when possible, eliminating active waits.
For this to happen, it would be cool having a function to query the state of the scheduler. For now I am using a global variable. Maybe it is not needed but I guess one shouldn't call vTaskDelay from within critical sections, so I also changed my port to modify the variable when entering critical sections and when finally exiting them. Is this neccesary? Do you think it would be worth adding to FreeRTOS?
How about http://www.freertos.org/a00021.html#xTaskGetSchedulerState
