MPI_Testall(3)

NAME
     MPI_Testall - Tests for the completion of all previously initiated
     communications

SYNOPSIS
     C:

          #include <mpi.h>

          int MPI_Testall( count, array_of_requests, flag,
          array_of_statuses )
          int        count;
          MPI_Request array_of_requests[];
          int        *flag;
          MPI_Status *array_of_statuses;


     C++:

          #include <mpi.h>

          static bool Request::Testall(
          int               count,
          Request           array_of_requests[])


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)

          LOGICAL flag
          INTEGER count, array_of_requests(*),
          array_of_statuses(MPI_STATUS_SIZE,*), ierror

          CALL MPI_TESTALL(count, array_of_requests(*), flag,
          array_of_statuses(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_Testall routine tests for the completion of all previously
     initiated communications.  This routine accepts the following parameters:

     count     Specifies the list length (integer)

     array_of_requests
               Specifies the array of requests (array of handles)
     flag      Returns a value of true if operation completed (logical)

     array_of_statuses
               Returns an array of status objects (array of status)

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