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.
