EventBufferEvent::__construct — Constructs EventBufferEvent object

### 説明

public function EventBufferEvent::__construct(
EventBase `$base` ,
mixed `$socket` = `null` ,
int `$options` = 0 ,
callable `$readcb` = `null` ,
callable `$writecb` = `null` ,
callable `$eventcb` = `null` ,
mixed `$arg` = `null`
)

Create a buffer event on a socket, stream or a file descriptor. Passing `null` to `socket` means that the socket should be created later, e.g. by means of EventBufferEvent::connect().

### パラメータ

`base`

  Event base that should be associated with the new buffer event.

`socket`

  May be created as a stream(not necessarily by means of `sockets` extension)

`options`

  One of EventBufferEvent::OPT_* constants, or `0`.

`readcb`

  Read event callback. See About buffer event callbacks.

`writecb`

  Write event callback. See About buffer event callbacks.

`eventcb`

  Status-change event callback. See About buffer event callbacks.

`arg`

  A variable that will be passed to all the callbacks.
