[rabbitmq-discuss] Simple C Client to read from a Queue

Thu Sep 6 12:44:35 BST 2012

Hi Tim,

Thanks for the reply and sorry for the inconvenience if I have put the
message into a "wrong" thread.

Even before putting the mail I tried commenting out the loops, but still I
saw it does wait until a message is available in Queue.

Also, I found
http://rabbitmq.1065348.n5.nabble.com/Librabbitmq-c-API-td6134.html , that
they have referred to "amqp_basic_get", and was thinking that someone will
give some help in using amqp_basic_get. I couldn't find a reference
document for C API, but there are docs available for Java/Erlang..etc.. but
could not find any for C.  "amqp_basic_get" have not been used in the set
of example as well...

Actually I'm not a C developer, but a Java Developer, and my requirement is
bit urgent, that's why I was expecting such kind of a basic help. If I had
time, definitely I would have go through the code n will try to understand
more..

IMO, it would have been better If the documentation related to C libraries
are bit improved, so that it will be easy for new comers to understand..
