OCI: generic binds

[Andy]

I'm quite new to using OCI and I'm trying to find a way of creating a
function to handle all store procedures in a database, problem I'm
having is with the OCIBindByPos function and how to make the type of
data being returned/input to the stored procedure generic.

I the following set up....

..
..
..
char * arrData[200];
..
..
..

/* get the number of arguments*/
checkerr(errhp, OCIAttrGet((dvo id *) arglist, OCI_DTYPE_PARAM ,
(dvoid*)numArgs , (ub4*)0,(ub4)OC I_ATTR_NUM_PARA MS , errhp));

for (i=1; i<=numArgs;i++ ) {

OCIParamGet (arglist, OCI_DTYPE_PARAM , errhp, &arg, i);

OCIAttrGet ((dvoid *)arg, OCI_DTYPE_PARAM , (dvoid*)&atypec ode,
(ub4*)0, OCI_ATTR_DATA_T YPE, errhp);

OCIAttrGet ((dvoid *)arg, OCI_DTYPE_PARAM , (dvoid*)&amaxsi ze,
(ub4*)0, OCI_ATTR_DATA_S IZE, errhp);

checkerr( errhp, OCIBindByPos(st mthp, (dvoid*)&arrOCI Bind[i],
errhp, i, &arrData[i] ,(sword)amaxsiz e , atypecode , (dvoid *) 0,(ub2
*) 0, (ub2) 0, (ub4) 0, (ub4 *) 0, OCI_DEFAULT));
}


running my test harness for a stored procedure which takes two params,
a SQLT_INT and SQLT_AFC out I get "OCI_NO_DAT A found" from which
suggests to me that data is being druncated.

Can anyone suggest what I need to change? Or is there another way
altogether i should be going about this? any sample code would go down
a treat!!

Thanks,

Andy.
