(PECL amqp >= Unknown)

AMQPChannel::setPrefetchCount — Set the number of messages to prefetch from the broker

### Descrição

public void AMQPChannel::setPrefetchCount ( int `$count` )

Set the number of messages to prefetch from the broker during a call to AMQPQueue::consume() or AMQPQueue::get(). Any call to this method will automatically set the prefetch window size to 0, meaning that the prefetch window size setting will be ignored.

If the call to either AMQPQueue::consume() or AMQPQueue::get() is done with the `AMQP_AUTOACK` flag set, this setting will be ignored.

### Parâmetros

`count`

  The number of messages to prefetch.

### Erros

Throws AMQPConnectionException if the connection to the broker was lost.

### Valor Retornado

Retorna `TRUE` em caso de sucesso ou `FALSE` em caso de falha.
