Method Summary

Modifier and TypeMethod and Description
public default void
callback(long
a pointer to the memory used for the function's return value.

If the function is declared as returning void, then this value is garbage and should not be used.

Otherwise, the callback must fill the object to which this points, following the same special promotion behavior as LibFFI#ffi_call. That is, in most cases, ret points to an object of exactly the size of the type specified when CIF was constructed. However, integral types narrower than the system register size are widened. In these cases your program may assume that ret points to an ffi_arg object.
