cudaError_t cudaThreadGetCacheConfig ( enum cudaFuncCache *  pCacheConfig  )  On devices where the L1 cache and shared memory use the same hardware resources, this returns through pCacheConfig the preferred cache configuration for the current host thread. This is only a preference. The runtime will use the requested configuration if possible, but it is free to choose a different configuration if required to execute functions. This will return a pCacheConfig of cudaFuncCachePreferNone on devices where the size of the L1 cache and shared memory are fixed. The supported cache configurations are: cudaFuncCachePreferNone: no preference for shared memory or L1 (default) cudaFuncCachePreferShared: prefer larger shared memory and smaller L1 cache cudaFuncCachePreferL1: prefer larger L1 cache and smaller shared memory Parameters: pCacheConfig  - Returned cache configuration Returns: cudaSuccess, cudaErrorInitializationError Note: Note that this function may also return error codes from previous, asynchronous launches.
