Expand description

\brief Returns the CUDA context bound to the calling CPU thread.

Returns in \p *pctx the CUDA context bound to the calling CPU thread. If no context is bound to the calling CPU thread then \p *pctx is set to NULL and ::CUDA_SUCCESS is returned.

\param pctx - Returned context handle

\return ::CUDA_SUCCESS, ::CUDA_ERROR_DEINITIALIZED, ::CUDA_ERROR_NOT_INITIALIZED, \notefnerr
