124 Module Documentation 4.24 Version Management Functions • CUresult cuDriverGetVersion (int ∗driverVersion) Returns the CUDA driver version. 4.24.1 Detailed Description This section describes the version management functions of the low-level CUDA driver application programming interface. 4.24.2 Function Documentation 4.24.2.1 cuDriverGetVersion (int ∗ driverVersion) Returns in ∗driverVersion the version number of the installed CUDA driver. This function automatically returns CUDA_ERROR_INVALID_VALUE if the driverVersion argument is NULL. Parameters: driverVersion - Returns the CUDA driver version Returns: Note: CUDA_SUCCESS, CUDA_ERROR_INVALID_VALUE Note that this function may also return error codes from previous, asynchronous launches.

4.25 Context Management 125 4.25 Context Management Functions • 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 ctx) 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 ctx) Pushes a floating context on the current CPU thread. • CUresult cuCtxSynchronize (void) Block for a context’s tasks to complete. 4.25.1 Detailed Description This section describes the context management functions of the low-level CUDA driver application programming interface. 4.25.2 Function Documentation 4.25.2.1 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 the thread. Currently, the flags parameter must be 0. Parameters: pctx - Returned context handle of the current context flags - Context attach flags (must be 0) Generated for NVIDIA CUDA Library by Doxygen
