Struct template minimum

boost::mpi::minimum — Compute the minimum of two values.


// In header: <boost/mpi/operations.hpp>

template<typename T> 
struct minimum {
  // types
  typedef T first_argument_type; 
  typedef T second_argument_type;
  typedef T result_type;         

  // public member functions
  const T & operator()(const T &, const T &) const;


This binary function object computes the minimum of the two values it is given. When used with MPI and a type T that has an associated, built-in MPI data type, translates to MPI_MIN.

minimum public member functions

  1. const T & operator()(const T & x, const T & y) const;


    the minimum of x and y.
