It must be called before performing any other OpenGL interoperability operations. It may fail if the neededOpenGL driver facilities are not available. For usage of the Flags parameter, see cuCtxCreate().Parameters:pCtx - Returned CUDA contextFlags - Options for CUDA context creationdevice - Device on which to create the contextReturns:CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_-ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_OUT_OF_MEMORYGenerated on Wed Apr 1 16:11:42 2009 for NVIDIA CUDA Library by Doxygen
