Diese Funktion ist bis jetzt nicht dokumentiert. Es steht nur die Liste der Argumente zur Verfügung.
path
Path for the new node(file).
mode
Specifies both the permissions to use and the type of node to be
created. It should be a combination (using bitwise OR) of one of the
file types listed below and the permissions for the new node(e.g. 0640).
Possible file types are: EIO_S_IFREG
(regular file),
EIO_S_IFCHR
(character file),
EIO_S_IFBLK
(block special file),
EIO_S_IFIFO
(FIFO - named pipe) and
EIO_S_IFSOCK
(UNIX domain socket).
To specify permissions EIO_S_I* constants could be
used.
dev
If the file type is EIO_S_IFCHR
or
EIO_S_IFBLK
then dev specifies the major and minor
numbers of the newly created device special file. Otherwise
dev
ignored. See mknod(2) man page for
details.
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($data, $result);
$data
is custom
data passed to the request.
$result
contains
request-specific result value; basically, the value returned by corresponding
system call.
data
Arbitrary variable passed to callback
.
eio_mknod() returns request resource on success or FALSE
on error.
Beispiel #1 eio_mknod() example
<?php
// FIFO name
$temp_filename = "/tmp/eio-temp-fifo";
/* Is called when eio_mknod() finishes */
function my_mknod_callback($data, $result) {
$s = stat($data);
var_dump($s);
if ($result == 0) {
echo "eio_mknod_ok";
}
@unlink($data);
}
eio_mknod($temp_filename, EIO_S_IFIFO, 0,
EIO_PRI_DEFAULT, "my_mknod_callback", $temp_filename);
eio_event_loop();
?>
