I have an issue when registering a service via the Avahi API. Below is a small code file that produces the issue. In the code file I put a comment where the error code -49 ("Not supported") is returned by the library. What am I doing wrong??
I have Avahi 0.6.25 running on Fedora 13. Due to other restrictions I cannot upgrade to a higher version of Fedora and thus am "confined" to using Fedora 0.6.25 which is the highest version available in a binary version for this OS.
The configuration of Avahi (avahi-daemon.conf) is default and was not changed. The Avahi-daemon is running.
In the code file I removed all other error detection and handling to prevent a large code file which might be harder to understand. The service is registered on another domain that .local which is where it goes wrong. If I change the code below and replace AVAHI_PUBLISH_USE_WIDE_AREA with 0 (a zero) and "mydomain.com" with NULL, the service myservice._mytype._tcp.local can be found and resolved on another computer running Apple's Bonjour service.
