rfio_fseek (3)

#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);

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.

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

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.
