vkCmdPreprocessGeneratedCommandsNV(3)

C Specification

Commands can be preprocessed prior execution using the following command:

// Provided by VK_NV_device_generated_commands
void vkCmdPreprocessGeneratedCommandsNV(
    VkCommandBuffer                             commandBuffer,
    const VkGeneratedCommandsInfoNV*            pGeneratedCommandsInfo);

Parameters

commandBuffer is the command buffer which does the preprocessing.
pGeneratedCommandsInfo is a pointer to a VkGeneratedCommandsInfoNV structure containing parameters affecting the preprocessing step.
