thrust::bit_or

template<typename T = void> struct bit_or : public cuda::std::bit_or<void>

bit_or is a function object. Specifically, it is an Adaptable Binary Function. If f is an object of class bit_and<T>, and x and y are objects of class T, then f(x,y) returns x|y.

The following code snippet demonstrates how to use bit_or to take the bitwise OR of one device_vector of ints by another.

#include <thrust/device_vector.h>
#include <thrust/functional.h>
#include <thrust/sequence.h>
#include <thrust/fill.h>
#include <thrust/transform.h>
...
const int N = 1000;
thrust::device_vector<int> V1(N);
thrust::device_vector<int> V2(N);
thrust::device_vector<int> V3(N);

thrust::sequence(V1.begin(), V1.end(), 1);
thrust::fill(V2.begin(), V2.end(), 13);

thrust::transform(V1.begin(), V1.end(), V2.begin(), V3.begin(),
                  thrust::bit_or<int>());
// V3 is now {1|13, 2|13, 3|13, ..., 1000|13}
