/* A multi-pointer allocator
|

*

|
* When copying data structures from the user (such as a render pass), it's
|
|
* common to need to allocate data for a bunch of different things. Instead
|
|
* of doing several allocations and having to handle all of the error checking
|
|
* that entails, it can be easier to do a single allocation. This struct
|
|
* helps facilitate that. The intended usage looks like this:
|
|
*
|
|
* VK_MULTIALLOC(ma)
|
|
* vk_multialloc_add(&ma, &main_ptr, 1);
|
|
* vk_multialloc_add(&ma, &substruct1, substruct1Count);
|
|
* vk_multialloc_add(&ma, &substruct2, substruct2Count);
|
|
*
|
|
* if (!vk_multialloc_alloc(&ma, pAllocator, VK_ALLOCATION_SCOPE_FOO))
|
|
* return vk_error(VK_ERROR_OUT_OF_HOST_MEORY);
