+/** @warning The APR_LARGEFILE flag only has effect on some platforms
+ * where sizeof(apr_off_t) == 4. Where implemented, it allows opening
+ * and writing to a file which exceeds the size which can be
+ * represented by apr_off_t (2 gigabytes). When a file's size does
+ * exceed 2Gb, apr_file_info_get() will fail with an error on the
+ * descriptor, likewise apr_stat()/apr_lstat() will fail on the
+ * filename. apr_dir_read() will fail with APR_INCOMPLETE on a
+ * directory entry for a large file depending on the particular
+ * APR_FINFO_* flags. Generally, it is not recommended to use this
+ * flag. */
