In the c world integral types are a bit more complicated. So for 
reference take a look at the table on [0].
As long as you have a pointer to a piece of data such as int* or void* 
you should be free to dereference it to get the value.

Such as:

extern(C) int* myCFunc();

void main() {
   int value = *myCFunc();
}
