fseeko
POSIX specification:
http://www.opengroup.org/onlinepubs/9699919799/functions/fseeko.html
Gnulib module: fseeko
Portability problems fixed by Gnulib:
fseeko
in <stdio.h>
is not enabled by default
on some platforms:
glibc 2.3.6, OSF/1 5.1.
off_t
is a 32-bit type, fseeko
does not work
correctly with files larger than 2 GB. (Cf. AC_SYS_LARGEFILE
.)
Portability problems not fixed by Gnulib:
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.
