mismatch(exec, first1, last1, first2)#

template<typename DerivedPolicy, typename InputIterator1, typename InputIterator2>
thrust::pair<InputIterator1, InputIterator2> thrust::mismatch(
const thrust::detail::execution_policy_base<DerivedPolicy> &exec,
InputIterator1 first1,
InputIterator1 last1,
InputIterator2 first2,
)#

mismatch finds the first position where the two ranges [first1, last1) and [first2, first2 + (last1 - first1)) differ. The two versions of mismatch use different tests for whether elements differ.

This version of mismatch finds the first iterator i in [first1, last1) such that *i == *(first2 + (i - first1)) is false. The return value is a pair whose first element is i and whose second element is *(first2 + (i - first1)). If no such iterator i exists, the return value is a pair whose first element is last1 and whose second element is *(first2 + (last1 - first1)).

The algorithm’s execution is parallelized as determined by exec.
