I don't think we need isNil. My preferred solution would be to add a couple of methods that the application can use to determine how to process the response, e.g.: bool XrdSsiRespInfo::hasMetadata() { return mdlen > 0; } bool XrdSsiRespInfo::hasData() { return blen > 0; } -- You are receiving this because you commented.
