using pthread or std::thread under Xenomai

Hello

I have an existing real-time component that was developed using Orocos on Xenomai

on the component, there is a thread that running not in real-time using pthread 

I need to introduce some locking mechanisms due to shared resource

I want to use "std" functions to accomplish it as it seems to me safer and also I know more about this

should I convert the pthread to std::thread?
