[rabbitmq-discuss] socket read timeout in rabbitmq-c

[alex chen]

thanks Scott for the suggestion!  We actually use amqp_data_in_buffer+select to wait for the frames to be consumed.  However, it is not easy to this for rpc like calls such as login/channel_open, because they call send+wait inside the function.  there is no way to insert the select() between the send_method and wait_frame().

You can pull the

amqp_get_sockfd
and then you can

amqp_data_in_buffer

If amqp_data_in_buffer returns true, then

If it returns false, select on the sockfd from

if there is data to be retrieved.

Only then
