C Specification

The generation of commands on the device requires a preprocess buffer. To retrieve the memory size and alignment requirements of a particular execution state call:

// Provided by VK_NV_device_generated_commands
void vkGetGeneratedCommandsMemoryRequirementsNV(
    VkDevice                                    device,
    const VkGeneratedCommandsMemoryRequirementsInfoNV* pInfo,
    VkMemoryRequirements2*                      pMemoryRequirements);

Parameters

  • device is the logical device that owns the buffer.

  • pInfo is a pointer to an instance of the VkGeneratedCommandsMemoryRequirementsInfoNV structure containing parameters required for the memory requirements query.

  • pMemoryRequirements points to an instance of the VkMemoryRequirements2 structure in which the memory requirements of the buffer object are returned.
