NAME

       MPI_Win_Lock -  Starts an RMA access epoch

SYNOPSIS

       #include <mpi.h>
       int MPI_Win_lock(int lock_type, int rank, int assert, MPI_Win win)

INPUT PARAMETERS

       lock_type
              - either MPI_LOCK_EXCLUSIVE or MPI_LOCK_SHARED (state)
       rank   - rank of locked window (nonnegative integer)
       assert - program assertion (integer)
       win    - window object (handle)

NOTES

       This  function  is  currently not implemented in LAM/MPI.  It will return an MPI_ERR_OTHER
       run time error.

NOTES FOR FORTRAN

       All MPI routines in Fortran (except for MPI_WTIME  and  MPI_WTICK  )  have  an  additional
       argument  ierr  at  the  end  of  the  argument list.  ierr is an integer and has the same
       meaning as the  return  value  of  the  routine  in  C.   In  Fortran,  MPI  routines  are
       subroutines, and are invoked with the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.
