* @section pj_file_size_limit_sec Size Limits
*
* There may be limitation on the size that can be handled by the
* #pj_file_setpos() or #pj_file_getpos() functions. The API itself
* uses 64-bit integer for the file offset/position (where available);
* however some backends (such as ANSI) may only support signed 32-bit
* offset resolution.
*
* Reading and writing operation uses signed 32-bit integer to indicate
* the size.
