# vkCreateShaderModule(3) Manual Page

## Name

vkCreateShaderModule - Creates a new shader module object

Loading… please wait.

## C Specification

To create a shader module, call:

    // Provided by VK_VERSION_1_0
    VkResult vkCreateShaderModule(
        VkDevice                                    device,
        const VkShaderModuleCreateInfo*             pCreateInfo,
        const VkAllocationCallbacks*                pAllocator,
        VkShaderModule*                             pShaderModule);

## Parameters

- `device` is the logical device that creates the shader module.

- `pCreateInfo` is a pointer to a VkShaderModuleCreateInfo structure.

- `pAllocator` controls host memory allocation as described in the Memory Allocation chapter.

- `pShaderModule` is a pointer to a VkShaderModule handle in which the resulting shader module object is returned.

## Description

Once a shader module has been created, any entry points it contains can be used in pipeline shader stages as described in Compute Pipelines and Graphics Pipelines.

Note | If the `maintenance5` feature is enabled, shader module creation can be omitted entirely. Instead, applications should provide the VkShaderModuleCreateInfo structure directly in to pipeline creation by chaining it to VkPipelineShaderStageCreateInfo. This avoids the overhead of creating and managing an additional object.

Valid Usage

- VUID-vkCreateShaderModule-pCreateInfo-06904
  If `pCreateInfo` is not `NULL`, `pCreateInfo->pNext` must be `NULL` or a pointer to a valid instance of

  - VkShaderModuleValidationCacheCreateInfoEXT

  - VkValidationFeaturesEXT

Valid Usage (Implicit)

- VUID-vkCreateShaderModule-device-parameter
  `device` must be a valid VkDevice handle

- VUID-vkCreateShaderModule-pCreateInfo-parameter
  `pCreateInfo` must be a valid pointer to a valid VkShaderModuleCreateInfo structure

- VUID-vkCreateShaderModule-pAllocator-parameter
  If `pAllocator` is not `NULL`, `pAllocator` must be a valid pointer to a valid VkAllocationCallbacks structure

- VUID-vkCreateShaderModule-pShaderModule-parameter
  `pShaderModule` must be a valid pointer to a VkShaderModule handle

Return Codes

On success, this command returns

  - `VK_SUCCESS`

On failure, this command returns

  - `VK_ERROR_OUT_OF_HOST_MEMORY`

  - `VK_ERROR_OUT_OF_DEVICE_MEMORY`

  - `VK_ERROR_INVALID_SHADER_NV`
