Class GLFWDeallocateCallback

  • All Implemented Interfaces:
    java.lang.AutoCloseable, GLFWDeallocateCallbackI, org.lwjgl.system.CallbackI, org.lwjgl.system.NativeResource, org.lwjgl.system.Pointer

    public abstract class GLFWDeallocateCallback
    extends org.lwjgl.system.Callback
    implements GLFWDeallocateCallbackI
    The function pointer type for memory deallocation callbacks.

    This is the function pointer type for memory deallocation callbacks. A memory deallocation callback function has the following signature:

    
     void function_name(void* block, void* user)

    This function may deallocate the specified memory block. This memory block will have been allocated with the same allocator.

    This function may be called during Init but before the library is flagged as initialized, as well as during Terminate after the library is no longer flagged as initialized.

    The block address will never be NULL. Deallocations of NULL are filtered out before reaching the custom allocator.

    Note
    • The specified memory block will not be accessed by GLFW after this function is called.
    • This function should not call any GLFW function.
    • This function may be called from any thread that calls GLFW functions.

    Type

    
     void (*GLFWDeallocateCallbackI.invoke(long, long)) (
         void *block,
         void *user

      • create

        public static GLFWDeallocateCallback create​(long functionPointer)
        Creates a GLFWDeallocateCallback instance from the specified function pointer.
        Returns:
        the new GLFWDeallocateCallback
      • createSafe

        @Nullable
        public static GLFWDeallocateCallback createSafe​(long functionPointer)
        Like create, but returns null if functionPointer is NULL.
