How to do it...

We are going to create an application that uses the real-time scheduler:

1. In your working directory, ~/test, create a subdirectory called realtime.
2. Use your favorite text editor to create a realtime.cpp file in the realtime subdirectory.
3. Add all the necessary includes and namespaces:

#include <iostream>#include <system_error>#include <thread>#include <chrono>#include <pthread.h>using namespace std::chrono_literals;

4. Next, add a function that configures a thread to use the real-time scheduler:

void ConfigureRealtime(pthread_t thread_id, int priority) {    sched_param sch;    sch.sched_priority = 20;    if (pthread_setschedparam(thread_id,                              SCHED_FIFO, &sch)) {        throw std::system_error(errno,                 std::system_category(), "Failed to set ...
