Template Function thrust::find(InputIterator, InputIterator, const T&)

Function Documentation

template<typename InputIterator, typename T>
InputIterator thrust::find(InputIterator first, InputIterator last, const T &value)

find returns the first iterator i in the range [first, last) such that *i == value or last if no such iterator exists.

#include <thrust/find.h>
#include <thrust/device_vector.h>
...
thrust::device_vector<int> input(4);

input[0] = 0;
input[1] = 5;
input[2] = 3;
input[3] = 7;

thrust::device_vector<int>::iterator iter;

iter = thrust::find(input.begin(), input.end(), 3); // returns input.first() + 2
iter = thrust::find(input.begin(), input.end(), 5); // returns input.first() + 1
iter = thrust::find(input.begin(), input.end(), 9); // returns input.end()

Return

The first iterator i such that *i == value or last.

Parameters

• first: Beginning of the sequence to search.

• last: End of the sequence to search.

• value: The value to find.

Template Parameters

• InputIterator: is a model of Input Iterator and InputIterator's value_type is equality comparable to type T.

• T: is a model of EqualityComparable.
