Hi,
I have a problem calling a C function
from another C function - DirectFunctionCall*
cannot be used since some parameters may be NULL.
This dies:
FunctionCallInfoData fcinfo1;
InitFunctionCallInfoData(fcinfo1, NULL, 7, NULL, NULL);
/* arg[] and arnull[] are filled with correct values */
result = myfunc(&fcinfo1);
Also this also:
FunctionCallInfoData fcinfo1;
FmgrInfo flinfo1;
MemSet(&flinfo1, 0, sizeof(flinfo1));
flinfo1.fn_addr = myfunc;
flinfo1.fn_nargs = 7;
InitFunctionCallInfoData(fcinfo1, &flinfo1, 7, NULL, NULL);
/* arg[] and arnull[] are filled with correct values */
result = FunctionCallInvoke(&fcinfo1);
How to do it correctly? I am on PostgreSQL 8.1.9 currently.
