Maps the \fCcount\fP Direct3D resources in \fCppResources\fP for access by CUDA.
.PP
The resources in \fCppResources\fP 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.
.PP
This function provides the synchronization guarantee that any Direct3D calls issued before \fBcudaD3D9MapResources()\fP will complete before any CUDA kernels issued after \fBcudaD3D9MapResources()\fP begin.
.PP
If any of \fCppResources\fP have not been registered for use with CUDA or if \fCppResources\fP contains any duplicate entries then \fBcudaErrorInvalidResourceHandle\fP is returned. If any of \fCppResources\fP are presently mapped for access by CUDA then \fBcudaErrorUnknown\fP is returned.

This function is deprecated as of CUDA 3.0.
.RE
.PP
Registers the Direct3D resource \fCpResource\fP for access by CUDA.
.PP
If this call is successful, then the application will be able to map and unmap this resource until it is unregistered through \fBcudaD3D9UnregisterResource()\fP. Also on success, this call will increase the internal reference count on \fCpResource\fP. This reference count will be decremented when this resource is unregistered through \fBcudaD3D9UnregisterResource()\fP.
.PP
This call potentially has a high-overhead and should not be called every frame in interactive applications.
.PP
The type of \fCpResource\fP must be one of the following.
.PP
.IP "\(bu" 2
IDirect3DVertexBuffer9: No notes.
.IP "\(bu" 2
IDirect3DIndexBuffer9: No notes.
.IP "\(bu" 2
IDirect3DSurface9: Only stand-alone objects of type IDirect3DSurface9 may be explicitly shared. In particular, individual mipmap levels and faces of cube maps may not be registered directly. To access individual surfaces associated with a texture, one must register the base texture object.
.IP "\(bu" 2
IDirect3DBaseTexture9: When a texture is registered, all surfaces associated with all mipmap levels of all faces of the texture will be accessible to CUDA.
.PP
.PP
The \fCflags\fP argument specifies the mechanism through which CUDA will access the Direct3D resource. The following value is allowed:
.PP
.IP "\(bu" 2
\fBcudaD3D9RegisterFlagsNone\fP: Specifies that CUDA will access this resource through a \fCvoid*\fP. The pointer, size, and pitch for each subresource of this resource may be queried through \fBcudaD3D9ResourceGetMappedPointer()\fP, \fBcudaD3D9ResourceGetMappedSize()\fP, and \fBcudaD3D9ResourceGetMappedPitch()\fP respectively. This option is valid for all resource types.
.PP
.PP
Not all Direct3D resources of the above types may be used for interoperability with CUDA. The following are some limitations:
.PP
.IP "\(bu" 2
The primary rendertarget may not be registered with CUDA.
.IP "\(bu" 2
Resources allocated as shared may not be registered with CUDA.
.IP "\(bu" 2
Any resources allocated in D3DPOOL_SYSTEMMEM or D3DPOOL_MANAGED may not be registered with CUDA.
.IP "\(bu" 2
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.
.IP "\(bu" 2
Surfaces of depth or stencil formats cannot be shared.
.PP
.PP
If Direct3D interoperability is not initialized on this context, then \fBcudaErrorInvalidDevice\fP is returned. If \fCpResource\fP is of incorrect type (e.g, is a non-stand-alone IDirect3DSurface9) or is already registered, then \fBcudaErrorInvalidResourceHandle\fP is returned. If \fCpResource\fP cannot be registered then \fBcudaErrorUnknown\fP is returned.

Returns in \fC*pArray\fP an array through which the subresource of the mapped Direct3D resource \fCpResource\fP, which corresponds to \fCface\fP and \fClevel\fP may be accessed. The value set in \fCpArray\fP may change every time that \fCpResource\fP is mapped.

If \fCpResource\fP is not registered then \fBcudaErrorInvalidResourceHandle\fP is returned.

Returns in \fC*pPitch\fP and \fC*pPitchSlice\fP the pitch and Z-slice pitch of the subresource of the mapped Direct3D resource \fCpResource\fP, which corresponds to \fCface\fP and \fClevel\fP. The values set in \fCpPitch\fP and \fCpPitchSlice\fP may change every time that \fCpResource\fP is mapped.
.PP
The pitch and Z-slice pitch values may be used to compute the location of a sample on a surface as follows.
.PP
For a 2D surface, the byte offset of the sample at position \fBx\fP, \fBy\fP from the base pointer of the surface is:
.PP
\fBy\fP * \fBpitch\fP + (\fBbytes per pixel\fP) * \fBx\fP 
.PP
For a 3D surface, the byte offset of the sample at position \fBx\fP, \fBy\fP, \fBz\fP from the base pointer of the surface is:
.PP
\fBz*\fP \fBslicePitch\fP + \fBy\fP * \fBpitch\fP + (\fBbytes per pixel\fP) * \fBx\fP 
.PP
Both parameters \fCpPitch\fP and \fCpPitchSlice\fP are optional and may be set to NULL.

If \fCpResource\fP is not of type IDirect3DBaseTexture9 or one of its sub-types or if \fCpResource\fP has not been registered for use with CUDA, then \fBcudaErrorInvalidResourceHandle\fP is returned.
