NAME

rfio_lseek - positions/repositions a file  

SYNOPSIS

#include <sys/types.h>
#include "rfio_api.h"

off_t rfio_lseek (int s, off_t offset, int how);

Under Linux, for large files:
#define _LARGEFILE64_SOURCE
#include <sys/types.h>
#include "rfio_api.h"

off64_t rfio_lseek64 (int s, off64_t offset, int how);

For large files, under other systems:
#include <sys/types.h>
#include "rfio_api.h"

off64_t rfio_lseek64 (int s, off64_t offset, int how);  

DESCRIPTION

rfio_lseek positions/repositions to offset the file associated with the descriptor s generated by a previous rfio_open. how indicates how to interpret the offset value:
SEEK_SET
The offset is set from beginning of file.
SEEK_CUR
The offset is added to current position.
SEEK_END
The offset is added to current file size.

rfio_lseek64 performs the same function on large files using off64_t rather than off_t.  

RETURN VALUE

This routine returns -1 if the operation failed or the actual offset from the beginning of file. In case of failure, serrno is set appropriately.  

ERRORS

EBADF
s is not a valid descriptor.
EINVAL
incorrect value for how.
SENOSHOST
Host unknown.
SENOSSERV
Service unknown.
SETIMEDOUT
Timed out.
SEBADVERSION
Version ID mismatch.
SEINTERNAL
Internal error.
SECONNDROP
Connection closed by remote end.
