MPI_Test - Tests for the completion of a send or receive
       operation


SYNOPSIS

       C:

            #include <mpi.h>

            int MPI_Test ( request, flag, status )
            MPI_Request  *request;
            int          *flag;
            MPI_Status   *status;

       C++:

            #include <mpi.h>

            bool Request::Test()

       Fortran:

            INCLUDE "mpif.h" (or USE MPI)

            LOGICAL flag
            INTEGER request, status(MPI_STATUS_SIZE), ierror

            CALL MPI_TEST(request, flag, status(MPI_STATUS_SIZE), ierror)


STANDARDS

       This release implements the MPI 1.2 standard, as
       documented by the MPI Forum in the spring 1997 release of
       MPI:  A Message Passing Interface Standard.


DESCRIPTION

       The MPI_Test routine tests for the completion of a send or
       receive operation.  This routine accepts the following
       parameters:

       request   Specifies the communication request (handle)

       flag      Returns a value of true if operation completed
                 (logical)

       status    Returns the status object (status)

       ierror    Specifies the return code value for successful
                 completion, which is in MPI_SUCCESS.
                 MPI_SUCCESS is defined in the mpif.h file.
