count graphics resources in
Once unmapped, the resources in
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 cudaGraphicsUnmapResources() will complete before any subsequently issued graphics work begins.
resources contains any duplicate entries then cudaErrorInvalidResourceHandle is returned. If any of
resources are not presently mapped for access by Cuda then cudaErrorUnknown is returned.
|count ||- Number of resources to unmap |
|resources ||- Resources to unmap |
|stream ||- Stream for synchronization|
- cudaSuccess, cudaErrorInvalidResourceHandle, cudaErrorUnknown
- Note that this function may also return error codes from previous, asynchronous launches.
