public abstract class GLFWReallocateCallback extends org.lwjgl.system.Callback implements GLFWReallocateCallbackI
The function pointer type for memory reallocation callbacks.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, orNULL
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 duringTerminate
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 ofNULL
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.
