C Specification

To determine the memory requirements for a buffer resource without creating an object, call:

// Provided by VK_KHR_maintenance4
void vkGetDeviceBufferMemoryRequirementsKHR(
    VkDevice                                    device,
    const VkDeviceBufferMemoryRequirementsKHR*  pInfo,
    VkMemoryRequirements2*                      pMemoryRequirements);


  • device is the logical device intended to own the buffer.

  • pInfo is a pointer to a VkDeviceBufferMemoryRequirementsKHR structure containing parameters required for the memory requirements query.

  • pMemoryRequirements is a pointer to a VkMemoryRequirements2 structure in which the memory requirements of the buffer object are returned.


Valid Usage (Implicit)
  • VUID-vkGetDeviceBufferMemoryRequirementsKHR-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkGetDeviceBufferMemoryRequirementsKHR-pInfo-parameter
    pInfo must be a valid pointer to a valid VkDeviceBufferMemoryRequirementsKHR structure

  • VUID-vkGetDeviceBufferMemoryRequirementsKHR-pMemoryRequirements-parameter
    pMemoryRequirements must be a valid pointer to a VkMemoryRequirements2 structure
