Assume you want to use a featurethat is optional for systems to support. Describe three potential strategies to dealing with the possibility that the featuremight not be present on a system on which you want to run your program.

Use sysconf to determine if the feature is supported. If it is, use it. Otherwise, potential approaches are: 1. Reduce your program to use the least common denominator—whatever featurethat is supported universally that allows you to accomplish the task at hand.
2. If this is insuf?cient, consider providing your own implementation of the featurefor the platforms missing it.
3. If all else fails, you could run your program in a virtual machine using a guest operating system that provides the desired feature. You can communicate with the processes running in the host (native) operating system with sockets, if necessary
