Using OCIArray in Pro*C

Question

I have a stored procedure which takes a VARRY of user defined type as IN parameter and VARRAY of another user defined type as OUT parameter. I am calling this procedure from a Pro*C program.
I have used OTT interface to generate the OUT file and C header file.
Can you please let me know how to initialize the input and output parameters (OCIArray) when calling this stored procedure from Pro*C?
Here is the header file generated by OTT:
#ifndef ARRAY_ORACLE
# define ARRAY_ORACLE
#ifndef OCI_ORACLE
# include <oci.h>
#endif
typedef OCIRef empdet_ref;
typedef OCIArray emplist;
typedef OCIArray idlist;
struct empdet
OCINumber ID;
OCIString * NAME;
OCINumber SALARY;
OCIString * PROJECT;
typedef struct empdet empdet;
struct empdet_ind
OCIInd _atomic;
OCIInd ID;
OCIInd NAME;
OCIInd SALARY;
OCIInd PROJECT;
typedef struct empdet_ind empdet_ind;
#endif
And the ProC code looks like this:
emplist *elist;
idlist *ilist;
main()
EXEC SQL ALLOCATE :elist;
EXEC SQL EXECUTE
BEGIN
callemp1.getempdata1(:ilist,:elist);
END;
END-EXEC;
ilist is a list of employee ids (NUMBER).
elist is struct for employee details.
Thanks in advance,
Vivek

Answer 1

But PRO*c have given that error .is there any usage error. As explained earlier, that has nothing to do with pro*c. your posted code will not compile under a c compiler.
did you see the difference (in bold) between what you posted and the one I posted earlier?
the struct declaration was incomplete. You need fix that. Make that change and post if you still have errors.
Try posting a sample program that you are having trouble with along with the complete error message so we can see the issue.
