Class GLFWReallocateCallback
- All Implemented Interfaces:
AutoCloseable
,GLFWReallocateCallbackI
,org.lwjgl.system.CallbackI
,org.lwjgl.system.NativeResource
,org.lwjgl.system.Pointer
This is the function pointer type for memory reallocation callbacks. A memory reallocation callback function has the following signature:
void* function_name(void* block, size_t size, void* user)
This function must return a memory block at least size
bytes long, or NULL
if allocation failed. Note that not all parts of GLFW handle
allocation failures gracefully yet.
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.
Any memory allocated by this function will be deallocated during library termination or earlier.
The block address will never be NULL
and the size will always be greater than zero. Reallocations of a block to size zero are converted into
deallocations. Reallocations of NULL
to a non-zero size are converted into regular allocations.
Note
- The returned memory block must be valid at least until it is deallocated.
- This function should not call any GLFW function.
- This function may be called from any thread that calls GLFW functions.
