TRUE if the search was started (asynchronous mode);
FALSE if another search is already in progress for this CFNetServiceBrowser or if an error occurred.
This function uses a CFNetServiceBrowser to search for domains. The search continues until the search is canceled by calling
TRUE, this function searches only for domains in which services can be registered. If
FALSE, this function searches for domains that can be browsed for services. When a domain is found, the callback function specified when the CFNetServiceBrowser was created is called and passed an instance of a CFStringRef containing the domain that was found.
In asynchronous mode, this function returns
TRUE if the search was started. Otherwise, it returns
In synchronous mode, this function blocks until the search is stopped by calling
CFNet from another thread, in which case it returns
FALSE, or until an error occurs.
This function is thread safe.
For any one CFNetServiceBrowser, only one domain search or one service search can be in progress at the same time.
