Passing data to C-style interface
If you write a primitive operator in C++, use this code as an example of how to pass data to C-style interfaces.
Cast
int8 * to char * and pass pointer to C
interface.int8 * data_start = & myList[0];
char * data = static_cast<char *>(data);
size_t length = myList.size();
InterfaceFunction(data,length);
