eio_link — Create a hardlink for file
$path
,$new_path
,$pri
= EIO_PRI_DEFAULT,$callback
= NULL,$data
= NULL
eio_link() creates a hardlink
new_path
for a file specified by
path
.
path
Source file path.
new_path
Target file path.
pri
The request priority: EIO_PRI_DEFAULT
, EIO_PRI_MIN
, EIO_PRI_MAX
, or null
.
If null
passed, pri
internally is set to
EIO_PRI_DEFAULT
.
callback
callback
function is called when the request is done.
It should match the following prototype:
void callback(mixed $data, int $result[, resource $req]);
data
is custom data passed to the request.

request-specific result value; basically, the value returned by corresponding system call.
req
is optional request resource which can be used with functions like eio_get_last_error()
data
Arbitrary variable passed to callback
