Interface GLFWDeallocateCallbackI

  • All Superinterfaces:
    org.lwjgl.system.CallbackI, org.lwjgl.system.Pointer
    All Known Implementing Classes:
    GLFWDeallocateCallback
    Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

    @FunctionalInterface
    public interface GLFWDeallocateCallbackI
    extends org.lwjgl.system.CallbackI
    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 (*invoke(long, long)) (
         void *block,
         void *user
