Function template search_n

boost::compute::search_n — Substring matching algorithm.

Synopsis

// In header: <boost/compute/algorithm/search_n.hpp>


template<typename TextIterator, typename ValueType> 
  TextIterator 
  search_n(TextIterator t_first, TextIterator t_last, size_t n, 
           ValueType value, command_queue & queue = system::default_queue());

Description

Searches for the first occurrence of n consecutive occurrences of value in text [t_first, t_last). Space complexity: \Omega(distance(t_first, t_last))

Parameters:

`n`	Number of times value repeats
`queue`	Queue on which to execute
`t_first`	Iterator pointing to start of text
`t_last`	Iterator pointing to end of text
`value`	Value which repeats

Returns:
