Bu işlev hala belgelendirilmemiştir; sadece bağımsız değişken listesi mevcuttur.
pathPath 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.
priThe 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(mixed $data, int $result[, resource $req]);datais custom data passed to the request.
resultrequest-specific result value; basically, the value returned by corresponding system call.
reqis optional request resource which can be used with functions like eio_get_last_error().
data
Arbitrary variable passed to callback.
eio_mknod() returns request resource on success, başarısızlık durumunda false döner.
