tachyon::AllocationHooks
Memory functions a host gives the library, for the allocations that can be routed: Vulkan objects,...
Definition gui_allocation_hooks.h:15

tachyon::AllocationHooks::free
void(*) free(void *ptr, void *user)
Frees ptr, which may be null.
Definition gui_allocation_hooks.h:22

tachyon::AllocationHooks::user
void * user
passed to every call
Definition gui_allocation_hooks.h:23

tachyon::AllocationHooks::allocate
void *(*) allocate(size_t size, size_t alignment, void *user)
Returns size bytes aligned to alignment (a power of two).
Definition gui_allocation_hooks.h:17

tachyon::AllocationHooks::reallocate
void *(*) reallocate(void *ptr, size_t size, size_t alignment, void *user)
Resizes ptr, keeping its alignment; ptr may be null (then it allocates).
Definition gui_allocation_hooks.h:20

tachyon::AllocationHooks::IsSet
bool IsSet() const
The hooks are used only when all three functions are set.
