amqp_queue_declare() hangs if called when the broker is in connection.blocked state

[salcock]

System details

librabbitmq-c version: 0.10.0
rabbitmq-server version: 3.9.13
OS: Ubuntu 22.04
I'm using the standard Ubuntu packages for librabbitmq-dev and rabbitmq-server.

Description

If the broker is in a connection.blocked state (as described here, calls to amqp_queue_declare() will cause the calling program to hang indefinitely.

I think that the call to amqp_queue_declare() should instead return and set a suitable RPC reply type that would allow the caller to see that the declaration failed due to the broker being blocked.

I've tried calling amqp_simple_wait_frame_noblock() before attempting to declare the queue to try and catch the AMQP_CONNECTION_BLOCKED_METHOD method in the hope that would be an indication that the broker is blocked, but amqp_simple_wait_frame_noblock() only returns AMQP_STATUS_TIMEOUT. I'm assuming that this means AMQP_CONNECTION_BLOCKED_METHOD is only going to be generated in response to a publish attempt?

Is there any other way that I could try to detect that the connection is blocked before calling amqp_queue_declare() ?
