MPI_Test(3)

NAME
     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.
