boost::mpi::status — Contains information about a message that has been or can be received.
// In header: <boost/mpi/status.hpp> class status { public: // construct/copy/destruct (); (); // public member functions () ; () ; () ; () ; template<typename T> () ; (); () ; // public data members mutable m_count; };
This structure contains status information about messages that have been received (with communicator::recv) or can be received (returned from communicator::probe or communicator::iprobe). It permits access to the source of the message, message tag, error code (rarely used), or the number of elements that have been transmitted.
status public member functions() ;
Retrieve the source of the message.
() ;
Retrieve the message tag.
() ;
Retrieve the error code.
() ;
Determine whether the communication associated with this object has been successfully cancelled.
template<typename T> () ;
Determines the number of elements of type T contained in the message. The type T must have an associated data type, i.e., is_mpi_datatype<T>mpl::true_. In cases where the type T does not match the transmitted type, this routine will return an empty optional<int>.
