find_queues() [1/2]

std::tuple< bool, std::uint32_t, std::uint32_t > nngn::DeviceInfo::find_queues

(

)

const

Finds queue families that support graphics and presentation.

Returns

{found, graphics, present}. If a single family supports both types of operations, it is preferred and graphics and present will have the same value.

Here is the call graph for this function:

find_queues() [2/2]

std::tuple< bool, std::uint32_t, std::uint32_t > nngn::DeviceInfo::find_queues

(

const

Finds queue families that support graphics and presentation.

Returns

{found, graphics, present}. If a single family supports both types of operations, it is preferred and graphics and present will have the same value.

init() [1/2]

void nngn::DeviceInfo::init	(	VkSurfaceKHR	s,
		VkPhysicalDevice	d
	)

Initializes all members.

Must be called before any other operation.
