## Name

VkShaderInstrumentationMetricDescriptionARM - Structure specifying shader instrumentation metric properties

Loading… please wait.

## C Specification

The `VkShaderInstrumentationMetricDescriptionARM` structure is defined as:

    // Provided by VK_ARM_shader_instrumentation
    typedef struct VkShaderInstrumentationMetricDescriptionARM {
        VkStructureType    sType;
        void*              pNext;
        char               name[VK_MAX_DESCRIPTION_SIZE];
        char               description[VK_MAX_DESCRIPTION_SIZE];
    } VkShaderInstrumentationMetricDescriptionARM;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `name` is an array of VK_MAX_DESCRIPTION_SIZE `char` containing a null-terminated UTF-8 string which is a short human readable name for this shader instrumentation metric.

- `description` is an array of VK_MAX_DESCRIPTION_SIZE `char` containing a null-terminated UTF-8 string which is a human readable description for this shader instrumentation metric.

## Description

Valid Usage (Implicit)

- VUID-VkShaderInstrumentationMetricDescriptionARM-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_SHADER_INSTRUMENTATION_METRIC_DESCRIPTION_ARM

- VUID-VkShaderInstrumentationMetricDescriptionARM-pNext-pNext
  `pNext` must be `NULL`

- VUID-VkShaderInstrumentationMetricDescriptionARM-name-parameter
  `name` must be a null-terminated UTF-8 string whose length is less than or equal to VK_MAX_DESCRIPTION_SIZE

- VUID-VkShaderInstrumentationMetricDescriptionARM-description-parameter
  `description` must be a null-terminated UTF-8 string whose length is less than or equal to VK_MAX_DESCRIPTION_SIZE
