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.
