Deprecated
This function is deprecated as of CUDA 5.0.
This function is deprecated and should no longer be used. It is no longer necessary to
associate a CUDA context with a D3D10 device in order to achieve maximum interoperability
performance.
Parameters:
ppD3DDevice - Returned Direct3D device corresponding to CUDA context
Returns:

cuD3D10GetDevice
CUresult cuD3D10MapResources (unsigned int count, ID3D10Resource ** ppResources)
Deprecated
This function is deprecated as of CUDA 3.0.
Maps the count Direct3D resources in ppResources for access by CUDA.
The resources in ppResources may be accessed in CUDA kernels until they are unmapped.
Direct3D should not access any resources while they are mapped by CUDA. If an application
does so, the results are undefined.
This function provides the synchronization guarantee that any Direct3D calls issued before
cuD3D10MapResources() will complete before any CUDA kernels issued after
cuD3D10MapResources() begin.
If any of ppResources have not been registered for use with CUDA or if ppResources
contains any duplicate entries, then CUDA_ERROR_INVALID_HANDLE is returned. If any of
ppResources are presently mapped for access by CUDA, then CUDA_ERROR_ALREADY_MAPPED is
returned.
Parameters:
count - Number of resources to map for CUDA
ppResources - Resources to map for CUDA
Returns:
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED,
CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_HANDLE, CUDA_ERROR_ALREADY_MAPPED,
CUDA_ERROR_UNKNOWN
Note:
Note that this function may also return error codes from previous, asynchronous
launches.

cuGraphicsMapResources
CUresult cuD3D10RegisterResource (ID3D10Resource * pResource, unsigned int Flags)
Deprecated
This function is deprecated as of CUDA 3.0.
Registers the Direct3D resource pResource for access by CUDA.
If this call is successful, then the application will be able to map and unmap this
resource until it is unregistered through cuD3D10UnregisterResource(). Also on success,
this call will increase the internal reference count on pResource. This reference count
will be decremented when this resource is unregistered through
cuD3D10UnregisterResource().
This call is potentially high-overhead and should not be called every frame in interactive
applications.
The type of pResource must be one of the following.
• ID3D10Buffer: Cannot be used with Flags set to CU_D3D10_REGISTER_FLAGS_ARRAY.
• ID3D10Texture1D: No restrictions.
• ID3D10Texture2D: No restrictions.
• ID3D10Texture3D: No restrictions.
The Flags argument specifies the mechanism through which CUDA will access the Direct3D
resource. The following values are allowed.
• CU_D3D10_REGISTER_FLAGS_NONE: Specifies that CUDA will access this resource through a
CUdeviceptr. The pointer, size, and (for textures), pitch for each subresource of this
allocation may be queried through cuD3D10ResourceGetMappedPointer(),
cuD3D10ResourceGetMappedSize(), and cuD3D10ResourceGetMappedPitch() respectively. This
option is valid for all resource types.
• CU_D3D10_REGISTER_FLAGS_ARRAY: Specifies that CUDA will access this resource through a
CUarray queried on a sub-resource basis through cuD3D10ResourceGetMappedArray(). This
option is only valid for resources of type ID3D10Texture1D, ID3D10Texture2D, and
ID3D10Texture3D.
Not all Direct3D resources of the above types may be used for interoperability with CUDA.
The following are some limitations.
• The primary rendertarget may not be registered with CUDA.
• Resources allocated as shared may not be registered with CUDA.
• Textures which are not of a format which is 1, 2, or 4 channels of 8, 16, or 32-bit
integer or floating-point data cannot be shared.
• Surfaces of depth or stencil formats cannot be shared.
If Direct3D interoperability is not initialized on this context then
CUDA_ERROR_INVALID_CONTEXT is returned. If pResource is of incorrect type or is already
registered, then CUDA_ERROR_INVALID_HANDLE is returned. If pResource cannot be registered,
then CUDA_ERROR_UNKNOWN is returned.
Parameters:
pResource - Resource to register
Flags - Parameters for resource registration
Returns:
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED,
CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_INVALID_HANDLE,
CUDA_ERROR_OUT_OF_MEMORY, CUDA_ERROR_UNKNOWN
Note:
Note that this function may also return error codes from previous, asynchronous
launches.

CUresult cuD3D10ResourceGetMappedArray (CUarray * pArray, ID3D10Resource * pResource, unsigned
int SubResource)
Deprecated
This function is deprecated as of CUDA 3.0.
Returns in *pArray an array through which the subresource of the mapped Direct3D resource
pResource, which corresponds to SubResource may be accessed. The value set in pArray may
change every time that pResource is mapped.
If pResource is not registered, then CUDA_ERROR_INVALID_HANDLE is returned. If pResource
was not registered with usage flags CU_D3D10_REGISTER_FLAGS_ARRAY, then
CUDA_ERROR_INVALID_HANDLE is returned. If pResource is not mapped, then
CUDA_ERROR_NOT_MAPPED is returned.
For usage requirements of the SubResource parameter, see
cuD3D10ResourceGetMappedPointer().
Parameters:
pArray - Returned array corresponding to subresource
pResource - Mapped resource to access
SubResource - Subresource of pResource to access
Returns:
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED,

CUresult cuD3D10ResourceGetMappedPitch (size_t * pPitch, size_t * pPitchSlice, ID3D10Resource
* pResource, unsigned int SubResource)
Deprecated
This function is deprecated as of CUDA 3.0.
Returns in *pPitch and *pPitchSlice the pitch and Z-slice pitch of the subresource of the
mapped Direct3D resource pResource, which corresponds to SubResource. The values set in
pPitch and pPitchSlice may change every time that pResource is mapped.
The pitch and Z-slice pitch values may be used to compute the location of a sample on a
surface as follows.
For a 2D surface, the byte offset of the sample at position x, y from the base pointer of
the surface is:
y * pitch + (bytes per pixel) * x
For a 3D surface, the byte offset of the sample at position x, y, z from the base pointer
of the surface is:
z* slicePitch + y * pitch + (bytes per pixel) * x
Both parameters pPitch and pPitchSlice are optional and may be set to NULL.
If pResource is not of type IDirect3DBaseTexture10 or one of its sub-types or if pResource
has not been registered for use with CUDA, then CUDA_ERROR_INVALID_HANDLE is returned. If
pResource was not registered with usage flags CU_D3D10_REGISTER_FLAGS_NONE, then
CUDA_ERROR_INVALID_HANDLE is returned. If pResource is not mapped for access by CUDA, then
CUDA_ERROR_NOT_MAPPED is returned.
For usage requirements of the SubResource parameter, see
cuD3D10ResourceGetMappedPointer().
Parameters:
pPitch - Returned pitch of subresource
pPitchSlice - Returned Z-slice pitch of subresource

CUresult cuD3D10ResourceGetSurfaceDimensions (size_t * pWidth, size_t * pHeight, size_t *
pDepth, ID3D10Resource * pResource, unsigned int SubResource)
Deprecated
This function is deprecated as of CUDA 3.0.
Returns in *pWidth, *pHeight, and *pDepth the dimensions of the subresource of the mapped
Direct3D resource pResource, which corresponds to SubResource.
Because anti-aliased surfaces may have multiple samples per pixel, it is possible that the
dimensions of a resource will be an integer factor larger than the dimensions reported by
the Direct3D runtime.
The parameters pWidth, pHeight, and pDepth are optional. For 2D surfaces, the value
returned in *pDepth will be 0.

has not been registered for use with CUDA, then CUDA_ERROR_INVALID_HANDLE is returned.
For usage requirements of the SubResource parameter, see
cuD3D10ResourceGetMappedPointer().
Parameters:
pWidth - Returned width of surface
pHeight - Returned height of surface
pDepth - Returned depth of surface
pResource - Registered resource to access
SubResource - Subresource of pResource to access
Returns:
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED,

cuGraphicsSubResourceGetMappedArray
CUresult cuD3D10ResourceSetMapFlags (ID3D10Resource * pResource, unsigned int Flags)
Deprecated
This function is deprecated as of CUDA 3.0.
Set flags for mapping the Direct3D resource pResource.
Changes to flags will take effect the next time pResource is mapped. The Flags argument
may be any of the following.
• CU_D3D10_MAPRESOURCE_FLAGS_NONE: Specifies no hints about how this resource will be
used. It is therefore assumed that this resource will be read from and written to by
CUDA kernels. This is the default value.
• CU_D3D10_MAPRESOURCE_FLAGS_READONLY: Specifies that CUDA kernels which access this
resource will not write to this resource.
• CU_D3D10_MAPRESOURCE_FLAGS_WRITEDISCARD: Specifies that CUDA kernels which access this
resource will not read from this resource and will write over the entire contents of the
resource, so none of the data previously stored in the resource will be preserved.
If pResource has not been registered for use with CUDA, then CUDA_ERROR_INVALID_HANDLE is
returned. If pResource is presently mapped for access by CUDA then
CUDA_ERROR_ALREADY_MAPPED is returned.
Parameters:
pResource - Registered resource to set flags for
Flags - Parameters for resource mapping
Returns:
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED,
CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_INVALID_HANDLE,

Deprecated
This function is deprecated as of CUDA 3.0.
Unmaps the count Direct3D resources in ppResources.
This function provides the synchronization guarantee that any CUDA kernels issued before
cuD3D10UnmapResources() will complete before any Direct3D calls issued after
cuD3D10UnmapResources() begin.
If any of ppResources have not been registered for use with CUDA or if ppResources
contains any duplicate entries, then CUDA_ERROR_INVALID_HANDLE is returned. If any of
ppResources are not presently mapped for access by CUDA, then CUDA_ERROR_NOT_MAPPED is
returned.
Parameters:
count - Number of resources to unmap for CUDA
ppResources - Resources to unmap for CUDA
