MPI_File_close(3OpenMPI)                                                            MPI_File_close(3OpenMPI)



NAME
       MPI_File_close - Closes a file (collective).


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

       Fortran Syntax
           INCLUDE 'mpif.h'
           MPI_FILE_CLOSE(FH, IERROR)
                  INTEGER    FH, IERROR


C++ Syntax
       #include <mpi.h>
       void MPI::File::Close()


INPUT/OUTPUT PARAMETER
       fh        File handle (handle).


OUTPUT PARAMETER
       IERROR    Fortran only: Error status (integer).


DESCRIPTION
       MPI_File_close   first   synchronizes   file   state,  then  closes  the  file  associated  with  fh.
       MPI_File_close is a collective routine. The user is responsible for  ensuring  that  all  outstanding
       requests associated with fh have completed before calling MPI_File_close.


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++ functions 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.
