cudaError_t cudaMemset2DAsync ( void *  devPtr, size_t  pitch, int  value, size_t  width, size_t  height, cudaStream_t  stream = 0   ) Sets to the specified value value a matrix (height rows of width bytes each) pointed to by dstPtr. pitch is the width in bytes of the 2D array pointed to by dstPtr, including any padding added to the end of each row. This function performs fastest when the pitch is one that has been passed back by cudaMallocPitch(). cudaMemset2DAsync() is asynchronous with respect to the host, so the call may return before the memset is complete. The operation can optionally be associated to a stream by passing a non-zero stream argument. If stream is non-zero, the operation may overlap with operations in other streams. Parameters: devPtr  - Pointer to 2D device memory pitch  - Pitch in bytes of 2D device memory value  - Value to set for each byte of specified memory width  - Width of matrix set (columns in bytes) height  - Height of matrix set (rows) stream  - Stream identifier Returns: cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidDevicePointer Note: Note that this function may also return error codes from previous, asynchronous launches.
