EventBuffer::lock — Acquires a lock on buffer

### 说明

public function EventBuffer::lock(): void

Acquires a lock on buffer. Can be used in pair with EventBuffer::unlock() to make a set of operations atomic, i.e. thread-safe. Note, it is not needed to lock buffers for individual operations. When locking is enabled(see EventBuffer::enableLocking() ), individual operations on event buffers are already atomic.

### 参数
