Re: API Question

Hi Marvin

Please read the API Concepts manual at InfoCenter (Programming->APIs->API 
concepts); it explains all this stuff, and you will save yourself a lot of 
headaches if you do that first instead of asking questions as they arise - 
there are landmines out there if you don't get grounded. As to the error data 
structure, you will find in that manual that you have some options - use the 
QUSEC copy member from QSYSINC/QRPGLESRC or QSYSINC/QRPGSRC for ILE or OPM, 
resp. Or you can an 8-character string that is all x'00's. The former lets you 
get error information directly from that structure, the latter says the API 
should just use normal iSeries error handling. See the manual for more info.

When working with APIs that have an API Error Data structure as part of the 
return, how do I define it. I am attempting to work with APIs but keep 
getting 
a error: 
Additional Message Information 

Message ID . . . . . . : CPF9549 Severity . . . . . . . : 40 
Message type . . . . . : Escape 
Date sent . . . . . . : 11/22/06 Time sent . . . . . . : 11:56:26 

Message . . . . : Error addressing API Parameter. 
Cause . . . . . : An error occurred addressing parameter 8 of the 
QteRetrieveModuleViews API. The reason code was 2. The following are the 
reasons why this message is issued. 
1 -- A pointer was used that is not available for use while running in the 
current program state. 
2 -- A pointer was used which did not point to storage that could be 
addressed for the parameter. The pointer may be null or may point to 
storage that does not exist.

interfaces.

So from the depth of desperation hell, I ask you for help: How do I define 
the 
parameter in the prototype so that I won't get this error. I have tried a few 
things and nothing seems to work. 


For example: 

D xAPIErr likeds(APIERR) 

and 
D xAPIErr * 

But nothing seems to work. 

What am I doing wrong?
