NAME

rfio_fseek - positions/repositions a file  

SYNOPSIS

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

int rfio_fseek (FILE *fp, long offset, int whence);

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

int rfio_fseeko64 (FILE *fp, off64_t offset, int whence);

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

int rfio_fseeko64 (FILE *fp, off64_t offset, int whence);  

DESCRIPTION

rfio_fseek positions/repositions to offset the file associated with the descriptor fp generated by a previous rfio_fopen. whence 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_fseeko64 can be used with large files and allows to use a 64 bit offset rather than a long.  

RETURN VALUE

This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.  

ERRORS

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