How to handle on SMG$_BATSTIPRO

Hans Adriaanse — Tue, 16 Jan 2007 08:09:01 GMT

Hello,
I am writing an application with use of SMG routines. For a reasonable update of the sreen I use SMG$BEGIN_PASTEBOARD_UPDATE and when the update is ready I use SMG$END_PASTEBOARD_UPDATE. But now I receive as a return code for the last function SMG$_BATSTIPRO. According to the manual this means the function acted correctly, but batching is still in progress.

I cannot find how to react on this. My application fails because a read function cannot be done while batching is active.

Who has experience with this fenomena ??

Thanks in advance,
Hans

I would say that you nested BEGINS and when the END is not the last END expected, you get this warning.

Idem for BATWASOFF that indicates an END without BEGIN.

Hi Wim,

No that is not the case. I checked the begin_pasteboard_update and that returned SS$_NORMAL. In case an update is already in progress, it returns SMG$_BATWASON.

So that is not the problem. By the way begin/end_update_pasteboard maintains an internal counter to avoid this problem.

looking around using various internet searches a common approach appears to be to loop waiting until this condition is no longer reported.

while (smg$end_pasteboard_update(&pid) == SMG$_BATSTIPRO)
;

An alternative approach can be seen in newsmenu.c in

BATSTIPRO, batching is still in progress
Facility: SMG, Screen Management Facility
Explanation: A user tried to end batching (updating) with a call to
SMG$END_DISPLAY_UPDATE or SMG$END_PASTEBOARD_UPDATE.

This action did not terminate batching because there were more calls to begin
batching than to end batching.

User Action: None. An outer level routine may still need batching to be in
effect.

It is a matter of counting inner and outer calls to the function. Your remarks made me do this and finding the solution.

Thanx
