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.

This function provides the synchronization guarantee that any Direct3D calls issued before \fBcuD3D10MapResources()\fP will complete before any CUDA kernels issued after \fBcuD3D10MapResources()\fP begin.

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 \fBcuD3D10UnregisterResource()\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 \fBcuD3D10UnregisterResource()\fP.
.PP
This call is potentially 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
ID3D10Buffer: Cannot be used with \fCFlags\fP set to CU_D3D10_REGISTER_FLAGS_ARRAY.

ID3D10Texture1D: No restrictions.
.IP "\(bu" 2
ID3D10Texture2D: No restrictions.

ID3D10Texture3D: No restrictions.

.PP
The \fCFlags\fP argument specifies the mechanism through which CUDA will access the Direct3D resource. The following values are allowed.
.PP
.IP "\(bu" 2
CU_D3D10_REGISTER_FLAGS_NONE: Specifies that CUDA will access this resource through a \fBCUdeviceptr\fP. The pointer, size, and (for textures), pitch for each subresource of this allocation may be queried through \fBcuD3D10ResourceGetMappedPointer()\fP, \fBcuD3D10ResourceGetMappedSize()\fP, and \fBcuD3D10ResourceGetMappedPitch()\fP respectively. This option is valid for all resource types.
.IP "\(bu" 2
CU_D3D10_REGISTER_FLAGS_ARRAY: Specifies that CUDA will access this resource through a \fBCUarray\fP queried on a sub-resource basis through \fBcuD3D10ResourceGetMappedArray()\fP. This option is only valid for resources of type ID3D10Texture1D, ID3D10Texture2D, and ID3D10Texture3D.
.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.

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.

The pitch and Z-slice pitch values may be used to compute the location of a sample on a surface as follows.

Unmaps the \fCcount\fP Direct3D resources in \fCppResources\fP.
.PP
This function provides the synchronization guarantee that any CUDA kernels issued before \fBcuD3D10UnmapResources()\fP will complete before any Direct3D calls issued after \fBcuD3D10UnmapResources()\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 \fBCUDA_ERROR_INVALID_HANDLE\fP is returned. If any of \fCppResources\fP are not presently mapped for access by CUDA, then \fBCUDA_ERROR_NOT_MAPPED\fP is returned.

\fBParameters:\fP
.RS 4
\fIcount\fP - Number of resources to unmap for CUDA
