CC3220SF-LAUNCHXL: is mq_send safe to use in an ISR on FreeRTOS? (TIPOSIX)

Hi All,

FreeRTOS provides *ISR variants of its methods that can be used in an ISR. For example: 

My question is -- is mq_send coded in a way that is safe to use in an ISR? Or should I rely on using something like writing to a variable and then dispatching it in another task?

Thanks!
