◆ find_if_not() [2/2]

template<typename InputIterator , typename Predicate >
InputIterator thrust::find_if_not ( InputIterator  first,
InputIterator  last,
Predicate  pred 

find_if_not returns the first iterator i in the range [first, last) such that pred(*i) is false or last if no such iterator exists.

firstBeginning of the sequence to search.
lastEnd of the sequence to search.
predA predicate used to test range elements.
The first iterator i such that pred(*i) is false, or last.
