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.
