ftello
POSIX specification:
http://www.opengroup.org/onlinepubs/9699919799/functions/ftello.html
Gnulib module: ftello
Portability problems fixed by Gnulib:
ftello
in <stdio.h>
is not enabled by default
on some platforms:
glibc 2.3.6, OSF/1 5.1.
putc
that followed a
getc
call that reached EOF on some platforms:
Solaris 11 2010-11.
off_t
is a 32-bit type, ftello
does not work
correctly with files larger than 2 GB. (Cf. AC_SYS_LARGEFILE
.)
Portability problems not fixed by Gnulib:
fseek
on some
platforms:
HP-UX 11.
fflush
, ftell
, ftello
, fgetpos
behave incorrectly
on input streams that are opened in O_TEXT
mode and whose contents
contains Unix line terminators (LF), on some platforms: mingw, MSVC 9.
off_t
is a 64-bit type, but fseeko
is
not present, stream operations on files larger than 2 GB silently do
the wrong thing. This affects BSD/OS, which is mostly obsolete.
