Non-blocking FTP directory listing?

[Troy Rollins]

I'm interested in getting a non-blocking FTP directory listing. Using 
"PUT..." is a blocking operation. So, I was thing of using 
libURLftpCommand("Chdir",...) but I'm not quite sure where that is 
going to return to, as it doesn't seem to offer the familiar callback 
syntax as the other libURL stuff. libURLSetStatusCallback may apply... 
should I expect the standard parameters returned e.g. theURL, theStatus 
with theStatus containing the listing?

Or is there a different non-blocking technique for directory listings? 
libURLDownloadToFile doesn't seem quite what I want.

Anyone done this? Got an example of usage and syntax? Dave?

Thanks.
