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()
- 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.
