Expand description

Selects best memory type automatically. This flag is recommended for most common use cases.

When using this flag, if you want to map the allocation (using vmaMapMemory() or #VMA_ALLOCATION_CREATE_MAPPED_BIT), you must pass one of the flags: #VMA_ALLOCATION_CREATE_HOST_ACCESS_SEQUENTIAL_WRITE_BIT or #VMA_ALLOCATION_CREATE_HOST_ACCESS_RANDOM_BIT in VmaAllocationCreateInfo::flags.

It can be used only with functions that let the library know VkBufferCreateInfo or VkImageCreateInfo, e.g. vmaCreateBuffer(), vmaCreateImage(), vmaFindMemoryTypeIndexForBufferInfo(), vmaFindMemoryTypeIndexForImageInfo() and not with generic memory allocation functions.
