# VkPipelineCreationFeedback(3) Manual Page

## Name

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

Loading… please wait.

## C Specification

The `VkPipelineCreationFeedback` structure is defined as:

    // Provided by VK_VERSION_1_3
    typedef struct VkPipelineCreationFeedback {
        VkPipelineCreationFeedbackFlags    flags;
        uint64_t                           duration;
    } VkPipelineCreationFeedback;

or the equivalent

    // Provided by VK_EXT_pipeline_creation_feedback
    typedef VkPipelineCreationFeedback VkPipelineCreationFeedbackEXT;

## Members

- `flags` is a bitmask of VkPipelineCreationFeedbackFlagBits 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` is not set in `flags`, an implementation must not set any other bits in `flags`, and the values of all other `VkPipelineCreationFeedback` data members are undefined.
