17       [1mrfio_readlink [22mgets the content of the symbolic link
18identified by [4mpath[24m.

20       [4mbuf[24m content is not null terminated.
21       Symbolic link content can be truncated to [4mlength[24m if
22[4mbuf[24m is too small.

25       This   routine  returns  the  count  of  bytes  placed  in
26[4mbuf[24m if the operation
27       was successful or ‐1 if the operation failed.  In the lat‐
28ter case, [1mser‐[0m
