# \_\_gnu\_parallel::\_\_multiway\_merge\_3\_variant\_sentinel\_switch(3)

Switch for 3-way merging with \_\_sentinels turned off.

## NAME

\_\_gnu\_parallel::\_\_multiway\_merge\_3\_variant\_sentinel\_switch\< \_\_sentinels, \_RAIterIterator, \_RAIter3, \_DifferenceTp, \_Compare \> - Switch for 3-way merging with \_\_sentinels turned off.

## SYNOPSIS

\#include \<multiway\_merge.h\>

### Public Member Functions

\_RAIter3 **operator()** (\_RAIterIterator \_\_seqs\_begin, \_RAIterIterator \_\_seqs\_end, \_RAIter3 \_\_target, \_DifferenceTp \_\_length, \_Compare \_\_comp)\

## Detailed Description

### template\<bool \_\_sentinels, typename \_RAIterIterator, typename \_RAIter3, typename \_DifferenceTp, typename \_Compare\>

struct \_\_gnu\_parallel::\_\_multiway\_merge\_3\_variant\_sentinel\_switch\< \_\_sentinels, \_RAIterIterator, \_RAIter3, \_DifferenceTp, \_Compare \>"Switch for 3-way merging with \_\_sentinels turned off.

Note that 3-way merging is always stable!
