# \_\_gnu\_parallel::multiway\_merge\_4\_variant\_sentinel\_switch(3cxx)

## NAME

\_\_gnu\_parallel::multiway\_merge\_4\_variant\_sentinel\_switch\< sentinels, RandomAccessIteratorIterator, RandomAccessIterator3, \_DifferenceTp, Comparator \> -

## SYNOPSIS

### Public Member Functions

RandomAccessIterator3 **operator()** (RandomAccessIteratorIterator seqs\_begin, RandomAccessIteratorIterator seqs\_end, RandomAccessIterator3 target, \_DifferenceTp length, Comparator comp)\

## Detailed Description

### template\<bool sentinels, typename RandomAccessIteratorIterator, typename RandomAccessIterator3, typename \_DifferenceTp, typename Comparator\>struct \_\_gnu\_parallel::multiway\_merge\_4\_variant\_sentinel\_switch\< sentinels, RandomAccessIteratorIterator, RandomAccessIterator3, \_DifferenceTp, Comparator \>

Switch for 4-way merging with sentinels turned off.

Note that 4-way merging is always stable!
