FSEEKO

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);
.fi

DESCRIPTION

The fBfseeko()fP and fBftello()fP functions are identical to fBfseek()fP and fBftell()fP (see fseek(3)), respectively, except that the fIoffsetfP argument of fBfseeko()fP and the return value of fBftello()fP is of type fBoff_tfP instead of fBlongfP.

On many architectures both fBoff_tfP and fBlongfP are 32-bit types, but compilation with

#define _FILE_OFFSET_BITS 64

will turn fBoff_tfP into a 64-bit type.

NOTES

These functions are found on SysV-like systems. They are not present in libc4, libc5, glibc 2.0 but available since glibc 2.1.

CONFORMING TO

The fseeko and ftello functions conform to SUSv2.
