pid_t pid;

if ((pid = fork()) < 0)
    ...fork failed...
else if (pid == 0)
{
     ...create command line in array of char pointers argv...
     ...sort out I/O -- redirect stdin from /dev/null?...
     execvp(argv[0], argv);
     ...report exec failed on stderr...
     _exit(126);
}
...parent process...gets on with life...

Use fork() to create a new process, and exec*() to replace it with a new application.
