       GASS Referrals.

       Referrals

       The GASS Transfer API supports referring URL requests to alternate URLs via referrals. Referrals are
       essentially pointers to another URL or URLs which contain the same file as the original location which a
       client has requested of a server. Referrals may span multiple protocol schemes, though not all protocols
       may be able to generate referrals. For example, an HTTP server may refer a client to another HTTP server,
       an HTTPS server.

       Upon receiving a referred response from a server, a client should query the request handle to determine
       from where the file can be retrieved.

       Get the number of URLs in this referral.

       This function examines the referral to determine if the number of URLs which are contained in it. Each of

       Get a URL string from a referral.

       This function examines the referral to retrieve a URL string from it. A valid referal will contain one or
       more strings. They are indexed from 0 to the value returned by globus_gass_transfer_referral_get_count()
       - 1.

       The string returned by this function must not be freed by the caller. It will remain valid until the
       referral structure is destroyed.
