NAME
       MPI_File_get_atomicity - Returns current consistency semantics for data-access operations.

SYNTAX
       C Syntax
	   #include <mpi.h>
	   int MPI_File_get_atomicity(MPI_File fh, int *flag)

       Fortran Syntax
	   INCLUDE 'mpif.h'
	   MPI_FILE_GET_ATOMICITY(FH, FLAG, IERROR)
	    INTEGER FH, IERROR
	    LOGICAL FLAG

C++ Syntax
       #include <mpi.h>
       bool MPI::File::Get_atomicity() const

INPUT PARAMETER
       fh	 File handle (handle).

OUTPUT PARAMETER
       flag	 true if atomic mode is enabled, false if nonatomic mode is enabled (boolean).

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION
       MPI_File_get_atomicity  returns the current consistency semantics for data access operations on the set of file handles created by one col-
       lective MPI_File_open. If flag is true, atomic mode is currently enabled; if flag is false, nonatomic mode is currently enabled.

ERRORS
       Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ func-
       tions  do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism
       will be used to throw an MPI:Exception object.

       Before the error value is returned, the current MPI error handler is called. For MPI I/O function errors, the default error handler is  set
       to  MPI_ERRORS_RETURN. The error handler may be changed with MPI_File_set_errhandler; the predefined error handler MPI_ERRORS_ARE_FATAL may
       be used to make I/O errors fatal. Note that MPI does not guarantee that an MPI program can continue past an error.
