Why do you need to handle `kXR_waitresp` synchronously? The only reason for doing this that I can see, is when the server sends the corresponding `kXR_attn` immediately after `kXR_waitresp`. Which makes it kind of pointless to send `kXR_waitresp` in the first place. --- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/290#issuecomment-146161336 ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the XROOTD-DEV list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=XROOTD-DEV&A=1
