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.
