fseeko, ftello - seek to or report file position
#include <stdio.h> int fseeko(FILE *stream, off_t offset, int whence); off_t ftello(FILE *stream);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
The fseeko() and ftello() functions
are identical to fseek(3) and ftell(3)
(see fseek(3)), respectively, except that the
offset argument of fseeko() and the return
value of ftello() is of type
off_t instead of
On some architectures, both
32-bit types, but defining _FILE_OFFSET_BITS with the
value 64 (before including
any header files) will turn
off_t into a 64-bit type.
These functions are available under glibc since version 2.1.
POSIX.1-2001, POSIX.1-2008, SUSv2.
