Method Summary

Modifier and Type	Method and Description
public default long	address() Implements org.lwjgl.system.Pointer.address. Returns the raw pointer address as a `long` value.
public 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. ret, long a vector of pointers to memory holding the arguments to the function args) The Java method that will be called from native code when the native callback function is invoked.
public FFICIF	Returns: the CIF structure for this callback function getCallInterface() Returns the libffi Call Interface for this callback function.

public void callback(long ret, long args) The Java method that will be called from native code when the native callback function is invoked. Parameters ret: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`.

public void callback(long ret, long args)

The Java method that will be called from native code when the native callback function is invoked.

Parameters

ret: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.

args:long

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