PFN_vkFreeFunction

Application-defined memory free function

The type of pfnFree is:

typedef void (VKAPI_PTR *PFN_vkFreeFunction)(
    void*                                       pUserData,
    void*                                       pMemory);
  • pUserData is the value specified for VkAllocationCallbacks::pUserData in the allocator specified by the application.
  • pMemory is the allocation to be freed.

pMemory may be NULL, which the callback must handle safely. If pMemory is non-NULL, it must be a pointer previously allocated by pfnAllocation or pfnReallocation. The application should free this memory.
