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.
