.SH DESCRIPTION
.ft R
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
.I fh
from the user's buffer
.I buf
in
.I 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
.I status
are undefined.
.SH NOTES
.ft R
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.
.SH 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.
.sp
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.
