According to the question \" How to get Linux distribution name and version? \", to get the linux distro name and version, this works:

Answer 1

int writepipe[2];
if (pipe(writepipe) < 0) {
  perror("pipe");
  return 1;
}
int ret = fork();
if (ret < 0) {
  perror("fork");
  return 1;
}
else if (ret == 0) // child process
{
  dup2(writepipe[1],1); // set writepipe[1] as stdout
  // close fds
  close(writepipe[0]);
  close(writepipe[1]);
  execlp("lsb_release","lsb_release","-a",NULL); //TODO: Error checking
}
else // parent process
{
  int status;
  waitpid(ret,&status,0); //TODO: Error checking
  //do what you need
  //read output of lsb_release from writepipe[0]
}

It works for me
