(gethostname) → string? |
Returns a string for the current machine’s hostname (including its domain).
(getpid) → exact-integer? |
Returns an integer identifying the current process within the operating system.
(truncate-file file [n-bytes]) → void? |
file : path-string? |
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.
