NAME
MPI_File_write_all_end - Writes a file starting at the locations speci-
fied by individual file pointers; ending part of a split collective
routine (blocking).
SYNTAX
C Syntax
#include <mpi.h>
int MPI_File_write_all_end(MPI_File fh, void *buf, MPI_Status *status)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_FILE_WRITE_ALL_END(FH, BUF, STATUS, IERROR)
<type> BUF(*)
INTEGER FH, STATUS, IERROR
C++ Syntax
#include <mpi.h>
void MPI::File::Write_all_end(const void* buf, MPI::Status& status)
void MPI::File::Write_all_end(const void* buf)
INPUT/OUTPUT PARAMETER
fh File handle (handle).
INPUT PARAMETER
buf Initial address of buffer (choice).
OUTPUT PARAMETERS
status Status object (status).
IERROR Fortran only: Error status (integer).
DESCRIPTION
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 asso-
ciated 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.
NOTES
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 Sec-
tion 9.4.5 of the MPI-2 standard.
ERRORS
Almost all MPI routines return an error value; C routines as the value
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.
