NAME
fseeko, ftello - seek to or report file positionSYNOPSIS
#include <stdio.h> int fseeko(FILE *stream, off_t offset, int whence); off_t ftello(FILE *stream); .fi
DESCRIPTION
The fseeko() and ftello() functions are identical to fseek() and ftell() (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 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).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.CONFORMING TO
