The type of pfnReallocation is:
typedef void* (VKAPI_PTR *PFN_vkReallocationFunction)(
void* pUserData,
void* pOriginal,
size_t size,
size_t alignment,
VkSystemAllocationScope allocationScope);If the reallocation was successful, pfnReallocation must return an allocation with enough space for size bytes, and the contents of the original allocation from bytes zero to min(original size, new size) - 1 must be preserved in the returned allocation. If size is larger than the old size, the contents of the additional space are undefined. If satisfying these requirements involves creating a new allocation, then the old allocation should be freed.
If pOriginal is NULL, then pfnReallocation must behave equivalently to a call to VkAllocationFunction with the same parameter values (without pOriginal).
If size is zero, then pfnReallocation must behave equivalently to a call to VkFreeFunction with the same pUserData parameter value, and pMemory equal to pOriginal.
If pOriginal is non-NULL, the implementation must ensure that alignment is equal to the alignment used to originally allocate pOriginal.
If this function fails and pOriginal is non-NULL the application must not free the old allocation.
pfnReallocation must follow the same rules for return values as PFN_vkAllocationFunction.
