MPI_File_write_all_end - Writes a file starting at the locations specified
by individual file pointers; ending part of a split collective routine
(blocking).
C Syntax
#include <mpi.h>
int MPI_File_write_all_end(MPI_File fh, void *buf, MPI_Status *status)
INCLUDE ’mpif.h’
MPI_FILE_WRITE_ALL_END(FH, BUF, STATUS, IERROR)
<type> BUF(*)
INTEGER FH, STATUS, IERROR
#include <mpi.h>
void MPI::File::Write_all_end(const void* buf, MPI::Status& status)
void MPI::File::Write_all_end(const void* buf)
- fh
- File handle (handle).
- buf
- Initial
address of buffer (choice).
- status
- Status object (status).
- IERROR
- Fortran only: Error status (integer).
MPI_File_write_all_end
is the ending part of a split collective routine that stores the number
of elements actually written into the file associated with fh from the
user’s buffer buf in status. MPI_File_write_all_end blocks until the operation
initiated by MPI_File_write_all_begin completes. The data is written into
those parts of the file specified by the current view. All other fields
of status are undefined.
All the nonblocking collective routines
for data access are "split" into two routines, each with _begin or _end
as a suffix. These split collective routines are subject to the semantic
rules described in Section 9.4.5 of the MPI-2 standard.
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.
