# PFN_vkGetInstanceProcAddrLUNARG(3) Manual Page

## Name

PFN_vkGetInstanceProcAddrLUNARG - Type definition for vkGetInstanceProcAddr

Loading… please wait.

## C Specification

The type of PFN_vkGetInstanceProcAddrLUNARG is:

    // Provided by VK_LUNARG_direct_driver_loading
    typedef PFN_vkVoidFunction (VKAPI_PTR *PFN_vkGetInstanceProcAddrLUNARG)(
        VkInstance instance, const char* pName);

## Parameters

- `instance` is a VkInstance handle.

- `pName` is the name of a Vulkan command.

## Description

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`.

| Note 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.
