+ *
+ * This is the secure replacement for tmpfile() that does not exist in
+ * GLIBC.  The function uses the Linux specific %O_TMPFILE and %O_EXCL
+ * for security.  When the %FILE is fclose()'ed the file contents is
+ * lost.  The file is hidden in the %_PATH_TMP directory on the system.
+ *
+ * Returns:
+ * An open %FILE pointer, or %NULL on error.
