16 On Windows, this function returns a file handle in @code{O_TEXT} mode by
17 default; this means that it translates '\n' to CR/LF by default. Use the
18 @code{O_BINARY} flag if you need reliable binary I/O.
20 On platforms where @code{off_t} is a 32-bit type, @code{open} may not work
21 correctly with files larger than 2 GB. The fix is to use the
22 @code{AC_SYS_LARGEFILE} macro.
