MPI_Waitany(3)

NAME
     MPI_Waitany - Waits for any specified send or receive to complete

SYNOPSIS
     C:

          #include <mpi.h>

          int MPI_Waitany(count, array_of_requests, index, status )
          int         count;
          MPI_Request array_of_requests[];
          int         *index;
          MPI_Status  *status;


     C++:

          #include <mpi.h>

          static int Request::Waitany(
          int               count,
          Request           array_of_requests[])


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)

          INTEGER count, array_of_requests(*), index, status(MPI_STATUS_SIZE), ierror

          CALL MPI_WAITANY(count, array_of_requests(*), index, 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_Waitany routine waits for any specified send or receive operation
     to complete.  This routine accepts the following parameters:

     count     Specifies the list length (integer).

     array_of_requests
               Specifies the array of requests (array of handles).

     index     Returns the index of the handle for the operation that
               completed.  For C, the range is 0 to count-1.  For Fortran, the
               range is 1 to count (integer).
     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.
