MPI_File_get_atomicity(3)

NAME
     MPI_File_get_atomicity - Returns the atomicity mode

SYNOPSIS
     C:

          #include "mpi.h"

          int MPI_File_get_atomicity (MPI_File fh, int *flag)


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)

          INTEGER fh, ierror
          LOGICAL flag

          CALL MPI_FILE_GET_ATOMICITY(fh, flag, ierror)


DESCRIPTION
     MPI_FILE_get_atomicity returns the current consistency semantics for data
     access operations on the set of file handles created by one collective
     open process.

     This routine accepts the following arguments:

     fh        Specifies the file handle (handle)

     flag      Specifies which mode to enable. If flag is true, atomic mode is
               enabled; if flag is false, nonatomic mode is enabled.

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

   Notes for Fortran
     All MPI objects (for example, MPI_Datatype, MPI_Comm, MPI_File) are of
     type INTEGER.
