C Specification

To dynamically control whether a special vertex index value is treated as restarting the assembly of primitives, call:

// Provided by VK_EXT_extended_dynamic_state2
void vkCmdSetPrimitiveRestartEnableEXT(
    VkCommandBuffer                             commandBuffer,
    VkBool32                                    primitiveRestartEnable);


  • commandBuffer is the command buffer into which the command will be recorded.

  • primitiveRestartEnable controls whether a special vertex index value is treated as restarting the assembly of primitives. It behaves in the same way as VkPipelineInputAssemblyStateCreateInfo::primitiveRestartEnable


This command sets the primitive restart enable for subsequent drawing commands when the graphics pipeline is created with VK_DYNAMIC_STATE_PRIMITIVE_RESTART_ENABLE set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineInputAssemblyStateCreateInfo::primitiveRestartEnable value used to create the currently active pipeline.

Valid Usage
  • VUID-vkCmdSetPrimitiveRestartEnable-None-08970
    At least one of the following must be true:

Valid Usage (Implicit)
  • VUID-vkCmdSetPrimitiveRestartEnable-commandBuffer-parameter
    commandBuffer must be a valid VkCommandBuffer handle

  • VUID-vkCmdSetPrimitiveRestartEnable-commandBuffer-recording
    commandBuffer must be in the recording state

  • VUID-vkCmdSetPrimitiveRestartEnable-commandBuffer-cmdpool
    The VkCommandPool that commandBuffer was allocated from must support graphics operations

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

  • Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized
