How to let the messages not show in shell terminal when use ipcBeginProcess ?

Charley,

If you're using ipcBeginProcess, then either you can use the "asynchronous" form and provide functions to consume the stdout and stderr output, or you can use the synchronous apprach and use ipcReadProcess. Output shouldn't appear in the xterm, since both stdout and stderr get sent to Virtuoso.

So I don't understand your problem.

Hi Andrew,

I use  ipcId = ipcBeginprocess("strmin ..."  nil dataHandle errorHandle log) , 

I see the message sent to the xterm . 

Thank you,

Charley 

Hi Andrew , 

I found the problem and know how to solve  it. , it's the log file  is used , it will sent message to xterm .

 If I use  ipcId = ipcBeginprocess("strmin ..."  nil dataHandle errorHandle log) ,  it will sent message to xterm

If I use  ipcId = ipcBeginprocess("strmin ..."  nil dataHandle errorHandle ) ,  it won't sent message to xterm

Thank you,

Charley 

Charley,

Presumably you didn't actually use those calls, because the function has a capital P  in Process, the second argument should be a string (e.g. "") rather than nil, and the log file name is the 6th argument, not the 5th (the 5th is an exit handler).

If I use:

procedure(MyDisplayStuff(cid data) printf("STUFF: %L\n" data))
procedure(MyExitHandler(cid status) printf("EXITED: %L\n" status))
ipcBeginProcess("/bin/ls" "" 'MyDisplayStuff 'MyDisplayStuff 'MyExitHandler "log")

Then I get nothing in the terminal, but I do get a file called log. If the file "log" is not writable for some reason, I get this in the xterm:

  Server: could not open/create logfile log

Is that what you mean?

Andrew.

Andrew , 

Thank you for correct me the usage and explain it.
