Returns a string for the current machine’s hostname (including its
domain).
(getpid) → exact-integer? |

operating system.
(truncate-file file [n-bytes]) → void? |

n-bytes : exact-nonnegative-integer? = 0 |
Truncates or extends the given file so that it is
n-bytes long. If the file does not exist, or if the process
does not have sufficient privilege to truncate the file, the
exn:fail exception is raised.
WARNING: under Unix, the implementation assumes that the system’s ftruncate function accepts a long long second argument.
