Determining applications for opening a file type

Is there an easy way to determine which applications can be used for
opening files of a given type or file extension?  I found
LSCopyApplicationsURLsForURL, but am hoping to find a way to get a list
of applications without needing to have an example file of the type for
the function call.

Thanks for any assistance,
