Vulkan Specification
Describes parameters of a memory allocation.

Valid Usage
- sType must be STRUCTURE_TYPE_MEMORY_ALLOCATE_INFO
- pNext must be NULL
- allocationSize must be less than or equal to the amount of memory available to the VkMemoryHeap specified by memoryTypeIndex and the calling command's VkDevice
- allocationSize must be greater than 0
Member documentation
- sType – the type of this structure. Must be: STRUCTURE_TYPE_MEMORY_ALLOCATE_INFO
- pNext – reserved for use by extensions
- allocationSize – the size of the allocation in bytes
- memoryTypeIndex – the memory type index, which selects the properties of the memory to be allocated, as well as the heap the memory will come from
