cudaError_t cudaHostUnregister ( void *  ptr  )  Unmaps the memory range whose base address is specified by ptr, and makes it pageable again. The base address must be the same one specified to cudaHostRegister(). Parameters: ptr  - Host pointer to memory to unregister Returns: cudaSuccess, cudaErrorInvalidValue Note: Note that this function may also return error codes from previous, asynchronous launches.
