C Specification

To determine the correct parameters to use when importing host pointers, call:

VkResult vkGetMemoryHostPointerPropertiesEXT(
    VkDevice                                    device,
    VkExternalMemoryHandleTypeFlagBits          handleType,
    const void*                                 pHostPointer,
    VkMemoryHostPointerPropertiesEXT*           pMemoryHostPointerProperties);

Valid Usage

• handleType must be EXTERNAL_MEMORY_HANDLE_TYPE_HOST_ALLOCATION_BIT_EXT or EXTERNAL_MEMORY_HANDLE_TYPE_HOST_MAPPED_FOREIGN_MEMORY_BIT_EXT
• pHostPointer must be a pointer aligned to an integer multiple of VkPhysicalDeviceExternalMemoryHostPropertiesEXT::minImportedHostPointerAlignment
• If handleType is EXTERNAL_MEMORY_HANDLE_TYPE_HOST_ALLOCATION_BIT_EXT, pHostPointer must be a pointer to host memory
• If handleType is EXTERNAL_MEMORY_HANDLE_TYPE_HOST_MAPPED_FOREIGN_MEMORY_BIT_EXT, pHostPointer must be a pointer to host mapped foreign memory

Valid Usage (Implicit)

• device must be a valid VkDevice handle
• handleType must be a valid VkExternalMemoryHandleTypeFlagBits value
• pHostPointer must be a pointer value
• pMemoryHostPointerProperties must be a valid pointer to a VkMemoryHostPointerPropertiesEXT structure

Return Codes

On success, this command returns

• SUCCESS

On failure, this command returns

• ERROR_OUT_OF_HOST_MEMORY
• ERROR_INVALID_EXTERNAL_HANDLE
