Function Documentation

   globus_result_t globus_gass_copy_cache_url_state (globus_gass_copy_handle_t * handle, char *
       url)
       Cache connections to an FTP or GridFTP server. Explicitly cache connections to URL server.
       When an URL is cached, the connection to the URL server will not be closed after a file
       transfer completes.

       Parameters
           handle Handle which will contain a cached connection to the URL server.
           url The URL of the FTP or GSIFTP server to cache.

       Returns
           This function returns GLOBUS_SUCCESS if successful, or a globus_result_t indicating
           the error that occurred.

   globus_result_t globus_gass_copy_flush_url_state (globus_gass_copy_handle_t * handle, char *
       url)
       Remove an FTP or GridFTP cached connection. Explicitly remove a cached connection to an
       FTP or GSIFTP server. If an idle connection to an FTP server exists, it will be closed.

       Parameters
           handle Handle which contains a cached connection to the URL server.
           url The URL of the FTP or GSIFTP server to remove.

       Returns
           This function returns GLOBUS_SUCCESS if successful, or a globus_result_t indicating
           the error that occurred.

   globus_result_t globus_gass_copy_handle_to_url (globus_gass_copy_handle_t * handle,
       globus_io_handle_t * source_handle, char * dest_url, globus_gass_copy_attr_t * dest_attr)
       Blocking transfer from an IO handle to an URL.

       Parameters
           handle The handle to perform the copy operation
           source_handle transfer data from this IO handle
           dest_url transfer data to this URL
           dest_attr Attributes describing how the transfer to the destination should be done

       Returns
           This function returns GLOBUS_SUCCESS if the transfer was completed successfully, or a
           result pointing to an object of one of the the following error types:

       Return values
           GLOBUS_GASS_COPY_ERROR_TYPE_NULL_PARAMETER The handle was equal to GLOBUS_NULL, so the
           transfer could not processed.
