Gnulib module: ftell

Portability problems fixed by Gnulib:
|
|
@itemize
|
|
@item
|
|
This function mistakenly succeeds on pipes on some platforms: mingw.
|
|
@item
|
|
This function produces incorrect results after @code{putc} that followed a
|
|
@code{getc} call that reached EOF on some platforms:
|
|
Solaris 11 2010-11.

Portability problems not fixed by Gnulib:
|
|
@itemize
|
|
@item
|
|
This function produces incorrect results immediately after @code{fseek} on some
|
|
platforms:
|
|
HP-UX 11.
|
|
@item
|
|
@code{fflush}, @code{ftell}, @code{ftello}, @code{fgetpos} behave incorrectly
|
|
on input streams that are opened in @code{O_TEXT} mode and whose contents
|
|
contains Unix line terminators (LF), on some platforms: mingw.
|
|
@item
|
|
On platforms where @code{long} is a 32-bit type, @code{ftell} does not work
|
|
correctly with files larger than 2 GB. The fix is to use @code{ftello}
|
|
instead and to invoke the @code{AC_SYS_LARGEFILE} macro.
