Manual Section... (3) - page: ftello
NAMEfseeko, ftello - seek to or report file position
#include <stdio.h> int fseeko(FILE *stream, off_t offset, int whence); off_t ftello(FILE *stream);
DESCRIPTIONThe 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 long.
On many architectures both off_t and long are 32-bit types, but compilation with
#define _FILE_OFFSET_BITS 64
RETURN VALUEOn successful completion, fseeko() returns 0, while ftello() returns the current offset. Otherwise, -1 is returned and errno is set to indicate the error.
ERRORSSee the ERRORS in fseek(3).
CONFORMING TOSUSv2, POSIX.1-2001.
NOTESThese functions are found on System V-like systems. They are not present in libc4, libc5, glibc 2.0 but are available since glibc 2.1.
