EventBuffer::read — Read data from an evbuffer and drain the bytes read

### 説明

public string EventBuffer::read ( int `$max_bytes` )

Read the first `max_bytes` from the buffer and drain the bytes read. If more `max_bytes` are requested than are available in the buffer, it only extracts as many bytes as available.

### パラメータ

`max_bytes`

  Maxmimum number of bytes to read from the buffer.

### 返り値

Returns string read, or `FALSE` on failure.

### 変更履歴

バージョン | 説明
--- | ---
1.6.0 | Renamed EventBuffer::read()(the old method name) to EventBuffer::read(). EventBuffer::read() now takes only `max_bytes` argument; returns string instead of integer.
