[gt-user] how to test if a file/dir exists

[Eilidh Grant]

Hi,

I'm working on the QCDGrid project at EPCC and I'm having some trouble  
using globus_ftp_client_exist to test if a file exists.

globus_ftp_client_exists returns GLOBUS_SUCCESS when the file or  
directory exists, but if the file doesn't exist it returns an error of  
type GLOBUS_FTP_CLIENT_ERROR_RESPONSE (the server responded with an  
error). This is the same error as is given for various problems such  
as the remote node isn't running globus, or the proxy is not valid  on  
the remote node. I can't distingush between a file not being found and  
another error. Can anyone help with this?

Thanks,
Eilidh
