RE: Pointer error when calling external function

Hi Alan,

In the SQL reference manual it is specified under 'CREATE FUNCTION':

GENERAL WITH NULLS
All applicable parameters are passed. The parameters are defined to be in
the following order:
v The first N parameters are the input parameters that are specified on
the
CREATE FUNCTION statement.
v An additional argument is passed for an indicator variable array.
v A parameter for the indicator variable for the result.
Note that the result is returned as a value of a C value returning
function.
For example:
return_val func(parameter-1, parameter-2, ...)

So you need to specify two extra parameters (the indicator variable array
for the input and the indicator variable for the result).

RE: Pointer error when calling external function

Thanks Joep
I thought it was more to do with the function as I had tested the
procedure in a small test RPG program with no problems
I dropped the function and created it again with COMMIT - see below
But my test is STILL failing with the same problem (using STRDBG)
You said
And you should be supplying extra parameters for a null map for the
input parameters and a null indicator variable for the result.

I didn’t make any changes for this
Is this the problem?
Where would this change need to be?
