MPI_File_close - Closes a file (collective).
C Syntax
#include <mpi.h>
int MPI_File_close(MPI_File *fh)
INCLUDE ’mpif.h’
MPI_FILE_CLOSE(FH, IERROR)
INTEGER FH, IERROR
#include <mpi.h>
void MPI::File::Close()
- fh
- File handle (handle).
- IERROR
- Fortran only: Error status (integer).
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.
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.
