Thanks,
but now I am a little confused about how to convert those datatypes to a char[] type.
I write long datatypes from char[] array into bound buffer:
long l = 0;
l = atol("long value");
long* pl = (long*) buffer;
void* b = pl+1;
memcpy(b, &l, sizeof(l));
I read long datatypes into char[] array from bound buffer:
char charrep[100] = "";
sprintf(charrep, "%d", *(long*) buffer);
result->setData(charrep);
How do I this for bigint datatypes (long long as I think) ?
Thanks
Lothar
