(PECL eio >= 0.0.1dev)
eio_mknod — Create a special or ordinary file
說明
string
$path,int
$mode,int
$dev,int
$pri = EIO_PRI_DEFAULT,callable
$callback = NULL,mixed
$data = NULL): resource
eio_mknod() creates ordinary or special(often) file.
本函式還未編寫文件，僅有參數列表。
參數
-
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_IFCHRorEIO_S_IFBLKthen dev specifies the major and minor numbers of the newly created device special file. Otherwisedevignored. See mknod(2) man page for details. -
pri -
請求的優先順序：
EIO_PRI_DEFAULT，EIO_PRI_MIN，EIO_PRI_MAX或null。如果是null，pri將設為EIO_PRI_DEFAULT。 -
callback -
callback函式在請求完成時被呼叫。其應匹配一下原型：void callback(mixed $data, int $result[, resource $req]);-
data -
傳遞給請求的用戶數據。
-
result -
針對請求的結果的值。通常是相應的系統呼叫返回的值。
-
req -
可選的請求資源，可被 eio_get_last_error() 之類的函式使用。
-
-
data -
Arbitrary variable passed to
callback.
返回值
eio_mknod() returns request resource on success, 或者在失敗時返回 false.
範例
示例 #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();
?>
