# vkGetPerformanceParameterINTEL(3) Manual Page

## Name

vkGetPerformanceParameterINTEL - Query performance capabilities of the device

## C Specification

Some performance query features of a device can be discovered with the call:

    // Provided by VK_INTEL_performance_query
    VkResult vkGetPerformanceParameterINTEL(
        VkDevice                                    device,
        VkPerformanceParameterTypeINTEL             parameter,
        VkPerformanceValueINTEL*                    pValue);

## Parameters

- `device` is the logical device to query.

- `parameter` is the parameter to query.

- `pValue` is a pointer to a VkPerformanceValueINTEL structure in which the type and value of the parameter are returned.

## Description
