Function template wait_any

boost::mpi::wait_any — Wait until any non-blocking request has completed.

Synopsis

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


template<typename ForwardIterator> 
  std::pair< status, ForwardIterator > 
  wait_any(ForwardIterator first, ForwardIterator last);

Description

This routine takes in a set of requests stored in the iterator range [first,last) and waits until any of these requests has been completed. It provides functionality equivalent to MPI_Waitany.

Parameters:

`first`	The iterator that denotes the beginning of the sequence of request objects.
`last`	The iterator that denotes the end of the sequence of request objects. This may not be equal to `first`.

Returns:

A pair containing the status object that corresponds to the completed operation and the iterator referencing the completed request.
