# VkPipelineCreationFeedbackEXT(3) Manual Page

## Name

VkPipelineCreationFeedbackEXT - Feedback about the creation of a pipeline or pipeline stage

## C Specification

The `VkPipelineCreationFeedbackEXT` structure is defined as:

    typedef struct VkPipelineCreationFeedbackEXT {
        VkPipelineCreationFeedbackFlagsEXT    flags;
        uint64_t                              duration;
    } VkPipelineCreationFeedbackEXT;

## Members

- `flags` is a bitmask of VkPipelineCreationFeedbackFlagBitsEXT providing feedback about the creation of a pipeline or of a pipeline stage.

- `duration` is the duration spent creating a pipeline or pipeline stage in nanoseconds.

## Description

If the `VK_PIPELINE_CREATION_FEEDBACK_VALID_BIT_EXT` is not set in `flags`, an implementation must not set any other bits in `flags`, and all other `VkPipelineCreationFeedbackEXT` data members are undefined.
