RFIO_LSEEK(3)						      Rfio Library Functions						     RFIO_LSEEK(3)

NAME
       rfio_lseek - positions/repositions a file

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

       off_t rfio_lseek (int s, off_t offset, int how);

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

       off64_t rfio_lseek64 (int s, off64_t offset, int how);

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

       off64_t rfio_lseek64 (int s, off64_t offset, int how);

DESCRIPTION
       rfio_lseek  positions/repositions to offset the file associated with the descriptor s generated by a previous rfio_open.  how 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_lseek64 performs the same function on large files using off64_t rather than off_t.

RETURN VALUE
       This routine returns -1 if the operation failed or the actual offset from the beginning of file. In case of failure, serrno is  set  appro-
       priately.

ERRORS
       EBADF	    s is not a valid descriptor.

       EINVAL	    incorrect value for how.

       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.
