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.
