C Specification
To determine the memory requirements for a buffer resource without creating an object, call:
// Provided by VK_VERSION_1_3
void vkGetDeviceBufferMemoryRequirements(
VkDevice device,
const VkDeviceBufferMemoryRequirements* pInfo,
VkMemoryRequirements2* pMemoryRequirements);
or the equivalent command
// Provided by VK_KHR_maintenance4
void vkGetDeviceBufferMemoryRequirementsKHR(
VkDevice device,
const VkDeviceBufferMemoryRequirements* pInfo,
VkMemoryRequirements2* pMemoryRequirements);
Parameters
-
device
is the logical device intended to own the buffer. -
pInfo
is a pointer to a VkDeviceBufferMemoryRequirements 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.
