cudaError_t cudaMemset ( void *  devPtr, int  value, size_t  count   ) Fills the first count bytes of the memory area pointed to by devPtr with the constant byte value value. Parameters: devPtr  - Pointer to device memory value  - Value to set for each byte of specified memory count  - Size in bytes to set Returns: cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidDevicePointer Note: Note that this function may also return error codes from previous, asynchronous launches.
