102 Module Documentation3.19 Version ManagementFunctions• CUresult cuDriverGetVersion (int ∗driverVersion)Returns the CUDA driver version.3.19.1 Detailed DescriptionThis section describes the version management functions of the low-level CUDA driver application programminginterface.3.19.2 Function Documentation3.19.2.1 CUresult cuDriverGetVersion (int ∗ driverVersion)Returns in ∗driverVersion the version number of the installed CUDA driver. This function automatically returnsCUDA_ERROR_INVALID_VALUE if the driverVersion argument is NULL.Parameters:driverVersion - Returns the CUDA driver versionReturns:Note:CUDA_SUCCESS, CUDA_ERROR_INVALID_VALUENote that this function may also return error codes from previous, asynchronous launches.Generated on Wed Apr 1 16:11:42 2009 for NVIDIA CUDA Library by Doxygen
3.20 Context Management 1033.20 Context ManagementFunctions• CUresult cuCtxAttach (CUcontext ∗pCtx, unsigned int Flags)Increment a context’s usage-count.• CUresult cuCtxCreate (CUcontext ∗pCtx, unsigned int Flags, CUdevice dev)Create a CUDA context.• CUresult cuCtxDestroy (CUcontext ctx)Destroy the current context or a floating CUDA context.• CUresult cuCtxDetach (CUcontext pCtx)Decrement a context’s usage-count.• CUresult cuCtxGetDevice (CUdevice ∗device)Returns the device ID for the current context.• CUresult cuCtxPopCurrent (CUcontext ∗pCtx)Pops the current CUDA context from the current CPU thread.• CUresult cuCtxPushCurrent (CUcontext NewCtx)Pushes a floating context on the current CPU thread.• CUresult cuCtxSynchronize (void)Block for a context’s tasks to complete.3.20.1 Detailed DescriptionThis section describes the context management functions of the low-level CUDA driver application programminginterface.3.20.2 Function Documentation3.20.2.1 CUresult cuCtxAttach (CUcontext ∗ pCtx, unsigned int Flags)Increments the usage count of the context and passes back a context handle in ∗pCtx that must be passed to cuCtxDetach()when the application is done with the context. cuCtxAttach() fails if there is no context current to thethread.Currently, the Flags parameter must be 0.Parameters:pCtx - Returned context handle of the current contextFlags - Context attach flags (must be 0)Generated on Wed Apr 1 16:11:42 2009 for NVIDIA CUDA Library by Doxygen
