public default void callback(long ret, long args)

Implements org.lwjgl.system.CallbackI.callback.

Doc from org.lwjgl.system.CallbackI.callback.

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

invoke	back to summary
public long invoke(long userptr, long sampledata, int numbytes) Parameters userptr:long the same pointer provided to `BufferCallbackSOFT` sampledata:long a pointer to the sample data buffer that should be filled in by the function numbytes:int the number of bytes needed to fill the sample data buffer for this invocation. Guaranteed to be greater than 0 and a multiple of the frame size for the format. Returns:long the number of bytes actually written, which must be equal to or less than `numbytes`. If the return value is less than `numbytes`, it's treated as the end of the buffer and the source will play any complete samples before stopping. Annotations @NativeType:void *

public long invoke(long userptr, long sampledata, int numbytes)

Parameters

userptr:long

the same pointer provided to BufferCallbackSOFT

sampledata:long

a pointer to the sample data buffer that should be filled in by the function

numbytes:int

the number of bytes needed to fill the sample data buffer for this invocation.

Guaranteed to be greater than 0 and a multiple of the frame size for the format.

Returns:long

the number of bytes actually written, which must be equal to or less than numbytes.

If the return value is less than numbytes, it's treated as the end of the buffer and the source will play any complete samples before stopping.
