Function Prototype
vkGetPhysicalDeviceDirectFBPresentationSupportEXT
Query physical device for presentation with DirectFB
To determine whether a queue family of a physical device supports presentation with DirectFB library, call:
VkBool32 vkGetPhysicalDeviceDirectFBPresentationSupportEXT(
VkPhysicalDevice physicalDevice,
uint32_t queueFamilyIndex,
IDirectFB* dfb);
physicalDevice
is the physical device.queueFamilyIndex
is the queue family index.dfb
is a pointer to theIDirectFB
main interface of DirectFB.
This platform-specific function can be called prior to creating a surface.
