<div style="direction:ltr; font-family:Tahoma; color:#000000; font-size:10pt">Hi Alan,<br>
<br>
Thanks for your earlier prompt replies. I am simulating a situation to test amqp_basic_publish. I modified the amqp_sendstring example to publish a message to the broker every 3 seconds. While the messages are getting published, I stop the broker using "rabbitmqctl
stop_app". As the broker is stopped, amqp_basic_publish is crashed.<br>
<br>
Code snippet as follows.<br>
<br>
<font color="993300">while(1)<br>
{<br>
amqp_basic_properties_t props;<br>
struct timeval t;<br>
int ret;<br>
<br>
t.tv_sec = 3;<br>
t.tv_usec = 0;<br>
select(0, NULL, NULL, NULL, &t);<br>
<br>
props._flags = AMQP_BASIC_CONTENT_TYPE_FLAG | AMQP_BASIC_DELIVERY_MODE_FLAG;<br>
props.content_type = amqp_cstring_bytes("text/plain");<br>
props.delivery_mode = 2; /* persistent delivery mode */<br>
printf("conn %u\n",conn);<br>
ret=amqp_basic_publish(conn,<br>
1,<br>
amqp_cstring_bytes(exchange),<br>
amqp_cstring_bytes(routingkey),<br>
1,<br>
0,<br>
&props,<br>
amqp_cstring_bytes(messagebody));<br>
printf("ret=%d\n",ret);<br>
}</font><br>
<br>
Program output:<br>
<font color="993300">conn 143663112<br>
ret=0<br>
conn 143663112<br>
ret=0<br>
conn 143663112</font><br>
<br>
First 2 published happened properly. After that I stopped broker. The program terminated. Considering this scenario, I would like to understand<br>
1. if there is a way to check the connection before I publish<br>
2. if the connection value becomes NULL, as we stop the broker.<br>
<br>
Thanks and regards,<br>
Shashank<br>
