PFN_vkGetInstanceProcAddrLUNARG

Type definition for vkGetInstanceProcAddr

The type of PFN_vkGetInstanceProcAddrLUNARG is:

typedef PFN_vkVoidFunction (VKAPI_PTR *PFN_vkGetInstanceProcAddrLUNARG)(
    VkInstance instance, const char* pName);
  • instance is a VkInstance handle.
  • pName is the name of a Vulkan command.

This type is compatible with the type of a pointer to the vkGetInstanceProcAddr command, but is used only to specify device driver addresses in VkDirectDriverLoadingInfoLUNARG::pfnGetInstanceProcAddr.

This type exists only because of limitations in the XML schema and processing scripts, and its name may change in the future. Ideally we would use the PFN_vkGetInstanceProcAddr type generated in the vulkan_core.h header.
