NAME

6       rfio_lseek - positions/repositions a file
7

SYNOPSIS

9       #include <sys/types.h>
10       #include "rfio_api.h"
11
12       off_t rfio_lseek (int s, off_t offset, int how);
13
14       Under Linux, for large files:
15       #define _LARGEFILE64_SOURCE
16       #include <sys/types.h>
17       #include "rfio_api.h"
18
19       off64_t rfio_lseek64 (int s, off64_t offset, int how);
20
21       For large files, under other systems:
22       #include <sys/types.h>
23       #include "rfio_api.h"
24
25       off64_t rfio_lseek64 (int s, off64_t offset, int how);
26

DESCRIPTION

28       rfio_lseek positions/repositions to offset the file associated with the
29       descriptor s generated by a previous rfio_open.  how indicates  how  to
30       interpret the offset value:
31
32              SEEK_SET     The offset is set from beginning of file.
33
34              SEEK_CUR     The offset is added to current position.
35
36              SEEK_END     The offset is added to current file size.
37
38       rfio_lseek64  performs  the  same function on large files using off64_t
39       rather than off_t.

RETURN VALUE

42       This routine returns -1 if the operation failed or  the  actual  offset
43       from the beginning of file. In case of failure, serrno is set appropri‐
44       ately.
