FSEEKO(3)		   Linux Programmer's Manual		     FSEEKO(3)

NAME
       fseeko, ftello - seek to or report file position

SYNOPSIS
       #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)):

       fseeko(), ftello():
	   _FILE_OFFSET_BITS == 64 || _POSIX_C_SOURCE >= 200112L ||
	   _XOPEN_SOURCE >= 600
	   (defining the obsolete _LARGEFILE_SOURCE macro also works)

DESCRIPTION
       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 long.

       On  many architectures both off_t and long are 32-bit types, but compiā€
       lation with

	      #define _FILE_OFFSET_BITS 64

       will turn off_t into a 64-bit type.

RETURN VALUE
       On successful completion, fseeko() returns 0,  while  ftello()  returns
       the  current  offset.   Otherwise,  -1  is returned and errno is set to
       indicate the error.

ERRORS
       See the ERRORS in fseek(3).

CONFORMING TO
       SUSv2, POSIX.1-2001.

NOTES
       These 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.
