Class CudaGraphicsInteropResourceCollection

Groupes several wrapped CUgraphicsResources together, so that the map() call to the CUDA API can be efficiently on all resources together.

MapAllResources()

Maps all graphics resources for access by CUDA.

The resources may be accessed by CUDA until they are unmapped. The graphics API from which the resource was registered 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 graphics calls issued before MapAllResources() will complete before any subsequent CUDA work issued in stream begins.

If any of the resources is presently mapped for access by CUDA then ErrorAlreadyMapped exception is thrown.

Declaration
public void MapAllResources()

MapAllResources(CUstream)

Maps all graphics resources for access by CUDA.

The resources may be accessed by CUDA until they are unmapped. The graphics API from which the resource was registered 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 graphics calls issued before MapAllResources() will complete before any subsequent CUDA work issued in stream begins.

If any of the resources is presently mapped for access by CUDA then ErrorAlreadyMapped exception is thrown.

Declaration
public void MapAllResources(CUstream stream)
Parameters
Type Name Description
CUstream stream

Remove(ICudaGraphicsInteropResource)

Declaration
public bool Remove(ICudaGraphicsInteropResource item)
Parameters
Type Name Description

Returns
Type Description
System.Boolean

UnmapAllResources()

Maps all graphics resources for access by CUDA.

The resources may be accessed by CUDA until they are unmapped. The graphics API from which the resource was registered 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 graphics calls issued before MapAllResources() will complete before any subsequent CUDA work issued in stream begins.

If any of the resources is presently mapped for access by CUDA then ErrorAlreadyMapped exception is thrown.

Declaration
public void UnmapAllResources()

UnmapAllResources(CUstream)

Unmaps all graphics resources.

Once unmapped, the resources may not be accessed by CUDA until they are mapped again.

This function provides the synchronization guarantee that any CUDA work issued in stream before UnmapAllResources() will complete before any subsequently issued graphics work begins.

If any of the resources are not presently mapped for access by CUDA then ErrorNotMapped exception is thrown.

Declaration
public void UnmapAllResources(CUstream stream)
Parameters
Type Name Description
CUstream stream
