31[1mDESCRIPTION[0m
32       [1mrfio_lseek  [22mpositions/repositions  to [4moffset[24m
33the file associated with the
34       descriptor  [4ms[24m  generated  by   a   previous   [1mr‐
35fio_open[22m.  [4mhow[24m indicates  how  to
36       interpret the [4moffset[24m value:
37
38              [1mSEEK_SET      [22mThe  offset is set from begin‐
39ning of file.
40
41              [1mSEEK_CUR     [22mThe offset is added to  current
42position.
43
44              [1mSEEK_END      [22mThe offset is added to current
45file size.
46
47       [1mrfio_lseek64  [22mperforms  the  same function on large
48files using off64_t
49       rather than off_t.
50
51[1mRETURN VALUE[0m
52       This  routine  returns  ‐1 if the operation failed or  the
53actual  offset
54       from the beginning of file. In case of failure,  [1mserrno

56       ately.
