The 1.4 branch has an update to allow this. You can take a look at the paho_c_sub and paho_c_pub samples to see how this works.
If you invoke paho_c_pub (on the 1.4 branch) like this:
paho_c_pub x -A sds -v
it will display a list of interfaces and addresses:
Interface name "lo0" family 0 addresses:
