Hi,
I have developed a simple TSP by implementing some basic TSPIs (e.g.
lineOpen, lineClose ...). I impelemented another simple TAPI program to open
line devices of my TSP and it works. All TSPI interface implementations
always return 0 in my TSP.
Then I changed the program a little, and make the TSP returns 0x80000044
(LINEERR_NOMEM) in TSPI_LineClose, however, my TAPI program still gets
success.
I could not figure out the issue here, it seems TAPI server will not just
pass the return value got from TSP?
Best Regards,
Nalan

Nalan,
please note that asynchronous TSPI functions (like TSPI_lineMakeCall) need to
return the dwRequestID (not 0) synchronously on success.
The final result of the operation is signalled via ASYNC_COMPLETION message.
See my TAPI and TSPI FAQ:
Q: Is there something special with asynchronous functions in TAPI2 ?

Why do you want to return LINEERR_NOMEM from TSPI_LineClose() ?

There is no on to one relation between TSPI and TAPI and its functions /
messages.
TAPI lineClose() doesn't get the return code from TSPI_lineClose() since
TAPISRV doesn't necessarily need to call TSPI_lineClose() when a TAPI app
called lineClose(). Only *after* the last TAPI app does a lineClose() on a
device then TSPI_lineClose() is called.

Thanks very much!
I understand that async TSPI functions return the final results in the
upcoming asynchronous responses.
I made my TSP return NOMEM only because I want to validate if TAPISRV uses
the return code of corresponding TSPI implementation.
From your answer I know there is no 1-1 mapping there.

If you just want to test the error return code processing in TAPISRV,
I suggest using (TSPI_)lineMakeCall for this.
There you should see the (synchronous) error return code from
TSPI_lineMakeCall() from your TSP as error return code for lineMakeCall() in
the calling TAPI app.
You may want to try it with MS TAPI Browser TB20 and/or with JulMar Phone.exe,
a TAPI test tool that is available with open source (TAPI2, C++):
http://www.julmar.com/tapi/
See my TAPI and TSPI FAQ:
Q: Where can I download TAPI Browser ?

Q: Is there a user guide available for TAPI Browser TB20 ?
