MPI_File_close(3)                  Open MPI                  MPI_File_close(3)



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.
