EIO_MKNOD(3) 1 EIO_MKNOD(3)
eio_mknod - Create a special or ordinary file.
SYNOPSIS
resource eio_mknod (string $path, int $mode, int $dev, [int $pri = EIO_PRI_DEFAULT], [callable $callback = NULL], [mixed $data =
NULL])
DESCRIPTION
eio_mknod(3) creates ordinary or special(often) file.
Warning
This function is currently not documented; only its argument list is available.
PARAMETERS
o $path
- Path for the new node(file).
o $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.
o $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 spe-
cial file. Otherwise $dev ignored. See mknod(2) man page for details.
o $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.
o $callback
-$callback function is called when the request is done. It should match the following prototype:
void callback(mixed $data, int $result[, resource $req]);
o $data
-is custom data passed to the request.
o $result
-request-specific result value; basically, the value returned by corresponding system call.
o $req
-is optional request resource which can be used with functions like eio_get_last_error(3)
o $data
- Arbitrary variable passed to $callback.
RETURN VALUES
eio_mknod(3) returns request resource on success or FALSE on error.
EXAMPLES
Example #1
eio_mknod(3) 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();
?>
