C Specification
While the core Vulkan API is not designed to capture incorrect usage, some circumstances still require return codes. Commands in Vulkan return their status via return codes that are in one of two categories:
-
Successful completion codes are returned when a command needs to communicate success or status information. All successful completion codes are non-negative values.
-
Run time error codes are returned when a command needs to communicate a failure that could only be detected at runtime. All runtime error codes are negative values.
All return codes in Vulkan are reported via VkResult return values. The possible codes are:
// Provided by VK_VERSION_1_0
typedef enum VkResult {
VK_SUCCESS = 0,
VK_NOT_READY = 1,
VK_TIMEOUT = 2,
VK_EVENT_SET = 3,

VK_INCOMPLETE = 5,

Description
-
VK_SUCCESS
Command successfully completed -
VK_NOT_READY
A fence or query has not yet completed -
VK_TIMEOUT
A wait operation has not completed in the specified time -
VK_EVENT_SET
An event is signaled -
VK_EVENT_RESET
An event is unsignaled -
VK_INCOMPLETE
A return array was too small for the result -
VK_SUBOPTIMAL_KHR
A swapchain no longer matches the surface properties exactly, but can still be used to present to the surface successfully.
-
VK_ERROR_OUT_OF_HOST_MEMORY
A host memory allocation has failed. -
VK_ERROR_OUT_OF_DEVICE_MEMORY
A device memory allocation has failed. -
VK_ERROR_INITIALIZATION_FAILED
Initialization of an object could not be completed for implementation-specific reasons. -
VK_ERROR_DEVICE_LOST
The logical or physical device has been lost. See Lost Device -
VK_ERROR_MEMORY_MAP_FAILED
Mapping of a memory object has failed. -
VK_ERROR_LAYER_NOT_PRESENT
A requested layer is not present or could not be loaded. -
VK_ERROR_EXTENSION_NOT_PRESENT
A requested extension is not supported. -
VK_ERROR_FEATURE_NOT_PRESENT
A requested feature is not supported. -
VK_ERROR_INCOMPATIBLE_DRIVER
The requested version of Vulkan is not supported by the driver or is otherwise incompatible for implementation-specific reasons. -
VK_ERROR_TOO_MANY_OBJECTS
Too many objects of the type have already been created. -
VK_ERROR_FORMAT_NOT_SUPPORTED
A requested format is not supported on this device. -
VK_ERROR_FRAGMENTED_POOL
A pool allocation has failed due to fragmentation of the pool’s memory. This must only be returned if no attempt to allocate host or device memory was made to accommodate the new allocation. This should be returned in preference toVK_ERROR_OUT_OF_POOL_MEMORY
, but only if the implementation is certain that the pool allocation failure was due to fragmentation. -
VK_ERROR_SURFACE_LOST_KHR
A surface is no longer available. -
VK_ERROR_NATIVE_WINDOW_IN_USE_KHR
The requested window is already in use by Vulkan or another API in a manner which prevents it from being used again. -
VK_ERROR_OUT_OF_DATE_KHR
A surface has changed in such a way that it is no longer compatible with the swapchain, and further presentation requests using the swapchain will fail. Applications must query the new surface properties and recreate their swapchain if they wish to continue presenting to the surface. -
VK_ERROR_INCOMPATIBLE_DISPLAY_KHR
The display used by a swapchain does not use the same presentable image layout, or is incompatible in a way that prevents sharing an image. -
VK_ERROR_OUT_OF_POOL_MEMORY
A pool memory allocation has failed. This must only be returned if no attempt to allocate host or device memory was made to accommodate the new allocation. If the failure was definitely due to fragmentation of the pool,VK_ERROR_FRAGMENTED_POOL
should be returned instead. -
VK_ERROR_INVALID_EXTERNAL_HANDLE
An external handle is not a valid handle of the specified type. -
VK_ERROR_FRAGMENTATION
A descriptor pool creation has failed due to fragmentation. -
VK_ERROR_INVALID_OPAQUE_CAPTURE_ADDRESS
A buffer creation or memory allocation failed because the requested address is not available. -
VK_ERROR_VALIDATION_FAILED
A command failed because invalid usage was detected by the implementation or a validation-layer. -
VK_ERROR_INVALID_PIPELINE_CACHE_DATA
The supplied pipeline cache data was not valid for the current implementation. -
VK_ERROR_NO_PIPELINE_MATCH
The implementation did not find a match in the pipeline cache for the specified pipeline, or VkPipelineOfflineCreateInfo was not provided to thevkCreate*Pipelines
function. -
VK_ERROR_UNKNOWN
An unknown error has occurred; either the application has provided invalid input, or an implementation failure has occurred.
If a command returns a runtime error, unless otherwise specified any output
parameters will have undefined contents, except that if the output
parameter is a structure with sType
and pNext
fields, those
fields will be unmodified.
Any structures chained from pNext
will also have undefined contents,
except that sType
and pNext
will be unmodified.
VK_ERROR_OUT_OF_*_MEMORY
errors do not modify any currently existing
Vulkan objects.
Objects that have already been successfully created can still be used by
the application.
If
VkPhysicalDeviceVulkanSC10Properties::deviceNoDynamicHostAllocations
is VK_TRUE
, VK_ERROR_OUT_OF_HOST_MEMORY
must not be returned
from any physical or logical device command which explicitly disallows it.
Note
As a general rule, |
VK_ERROR_UNKNOWN
will be returned by an implementation when an
unexpected error occurs that cannot be attributed to valid behavior of the
application and implementation.
Under these conditions, it may be returned from any command returning a
VkResult.
Note
|
Any command returning a VkResult may return
VK_ERROR_VALIDATION_FAILED
if a violation of valid usage is detected, even though commands do not
explicitly list this as a possible return code.
Performance-critical commands generally do not have return codes.
If a runtime error occurs in such commands, the implementation will defer
reporting the error until a specified point.
For commands that record into command buffers (vkCmd*
) runtime errors
are reported by vkEndCommandBuffer
.
Note
Implementations can also use https://registry.khronos.org/vulkansc/specs/1.0-extensions/html/vkspec.html#fault-handling to report runtime errors where suitable return values are not available or to provide more prompt notification of an error. |
