eio_mknod — Create a special or ordinary file.
$path
, int $mode
, int $dev
[, int $pri = EIO_PRI_DEFAULT
[, callable $callback = NULL
[, mixed $data = NULL ]]] )eio_mknod() creates ordinary or special(often) file.
本函数还未编写文档,仅有参数列表。
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 请求的优先级: EIO_PRI_DEFAULT , EIO_PRI_MIN , EIO_PRI_MAX 或 NULL 。如果是
NULL ,pri 将设为
EIO_PRI_DEFAULT 。
callback callback
函数在请求完成时被调用。其应匹配一下原型:
void callback(mixed $data, int $result[, resource $req]); data 传递给请求的用户数据。
result 针对请求的结果的值。通常是相应的系统调用返回的值。
req 可选的请求资源,可被 eio_get_last_error() 之类的函数使用。
data
Arbitrary variable passed to callback.
eio_mknod() returns request resource on success or FALSE on error.
Example #1 eio_mknod() example
<?php
// FIFO name
$temp_filename = "/tmp/eio-temp-fifo" ;
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 ();
?> 以上例程的输出类似于:
