MPI_File_write_at_all_end(3) Open MPI MPI_File_write_at_all_end(3)NAMEMPI_File_write_at_all_end - Writes a file at explicitly specified off‐
sets; ending part of a split collective routine (blocking).
SYNTAX
C Syntax
#include <mpi.h>
int MPI_File_write_at_all_end(MPI_File fh, const void *buf,
MPI_Status *status)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_FILE_WRITE_AT_ALL_END(FH, BUF, STATUS, IERROR)
<type> BUF(*)
INTEGER FH, STATUS(MPI_STATUS_SIZE), IERROR
C++ Syntax
#include <mpi.h>
void MPI::File::Write_at_all_end(const void* buf, MPI::Status& status)
void MPI::File::Write_at_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).
DESCRIPTIONMPI_File_write_at_all_end is the ending part of a split collective rou‐
tine that stores the number of elements actually written into the file
associated with fh in status. 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
of the function and Fortran routines in the last argument. C++ func‐
tions 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.
