/**
* 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 {@link GLFW#glfwInit Init} but before the library is flagged as initialized, as well as during {@link GLFW#glfwTerminate Terminate} after the library is no
* longer flagged as initialized.
*
* The block address will never be {@code NULL}. Deallocations of {@code 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 (*{@link #invoke}) (
* void *block,
* void *user
* )
*
* @since version 3.4
