(PECL eio >= 0.0.1dev)
eio_mknod — Create a special or ordinary file
Description
$path
, int $mode
, int $dev
[, int $pri
= EIO_PRI_DEFAULT
[, callable $callback
= NULL
[, mixed $data
= NULL
]]] ) : resourceeio_mknod() creates ordinary or special(often) file.
This function is currently not documented; only its argument list is available.
Parameters
-
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) andEIO_S_IFSOCK
(UNIX domain socket). To specify permissions EIO_S_I* constants could be used. -
dev
-
If the file type is
EIO_S_IFCHR
orEIO_S_IFBLK
then dev specifies the major and minor numbers of the newly created device special file. Otherwisedev
ignored. See mknod(2) man page for details. -
pri
-
The request priority:
EIO_PRI_DEFAULT
,EIO_PRI_MIN
,EIO_PRI_MAX
, orNULL
. IfNULL
passed,pri
internally is set toEIO_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.
-
result
-
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
.
Examples
Example #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();
?>
The above example will output something similar to:
array(26) { [0]=> int(17) [1]=> int(2337608) [2]=> int(4096) [3]=> int(1) [4]=> int(1000) [5]=> int(100) [6]=> int(0) [7]=> int(0) [8]=> int(1318241261) [9]=> int(1318241261) [10]=> int(1318241261) [11]=> int(4096) [12]=> int(0) ["dev"]=> int(17) ["ino"]=> int(2337608) ["mode"]=> int(4096) ["nlink"]=> int(1) ["uid"]=> int(1000) ["gid"]=> int(100) ["rdev"]=> int(0) ["size"]=> int(0) ["atime"]=> int(1318241261) ["mtime"]=> int(1318241261) ["ctime"]=> int(1318241261) ["blksize"]=> int(4096) ["blocks"]=> int(0) } eio_mknod_ok
