I am able to read but I am unable to print column headers ?
How can I print column headers after reading profile generic columns.
gxArray obj = pg->captureObjects;

Hi,

Check obj_CaptureObjectsToString. You need to read attribute #3 first.

Hello,

Hi,

cl_updateValue parse hex string and update value to the profile generic object.

Like this
ret = com_read(connection, object, 3);
gxReplyData reply;
reply_init(&reply);
ret = cl_updateValue(&connection->settings, object, 3, &reply.dataValue);

But it returns access violation error

Hi,

com_read calls this internally. You don't need to call it again.

In C obj_CaptureObjectsToString is undefined

Hi,

Call obj_toString. It calls obj_CaptureObjectsToString.

Thanks It works
char* data = NULL;
ret = obj_toString(object, &data);
if (data != NULL)
{
printf("%s", data);
free(data);
data = NULL;
}
