+/* get_tmpname() - create a tmp filename for a given filename
+ *
+ * If a tmpdir is defined, use that as the directory to put it in. Otherwise,
+ * the tmp filename is in the same directory as the given name. Note that
+ * there may be no directory at all in the given name!
+ *
+ * The tmp filename is basically the given filename with a dot prepended, and
+ * .XXXXXX appended (for mkstemp() to put its unique gunk in). We take care
+ * to not exceed either the MAXPATHLEN or NAME_MAX, especially the last, as
+ * the basename basically becomes 8 characters longer. In such a case, the
+ * original name is shortened sufficiently to make it all fit.
+ *
+ * If the make_unique arg is True, the XXXXXX string is replaced with a unique
+ * string that doesn't exist at the time of the check. This is intended to be
+ * used for creating hard links, symlinks, devices, and special files, since
+ * normal files should be handled by mkstemp() for safety.
+ *
+ * Of course, the only reason the file is based on the original name is to
+ * make it easier to figure out what purpose a temp file is serving when a
+ * transfer is in progress. */
