      default FFICIF getCallInterface()
      Description copied from interface: CallbackI
      Returns the libffi Call Interface for this callback function. [INTERNAL API]
      Specified by:
      getCallInterface in interface CallbackI
      Returns:
      the CIF structure for this callback function

    • callback

      default void callback(long ret, long args)
      Description copied from interface: CallbackI
      The Java method that will be called from native code when the native callback function is invoked.
      Specified by:
      callback in interface CallbackI
      Parameters:
      ret - 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(org.lwjgl.system.libffi.FFICIF, long, java.nio.ByteBuffer, org.lwjgl.PointerBuffer). 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.

      args - a vector of pointers to memory holding the arguments to the function
