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 Communication error.
