NAME
MPI_File_read_at_all_end - Reads a file at explicitly specified off-
sets; ending part of a split collective routine (blocking).
SYNTAX
C Syntax
#include <mpi.h>
int MPI_File_read_at_all_end(MPI_File fh, void *buf,
MPI_Status *status)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_FILE_READ_AT_ALL_END(FH, BUF, STATUS, IERROR)
<TYPE> BUF(*)
INTEGER FH, STATUS(MPI_STATUS_SIZE), IERROR
C++ Syntax
#include <mpi.h>
void MPI::File::Read_at_all_end(void* buf, MPI::Status& status)
void MPI::File::Read_at_all_end(void* buf)
INPUT PARAMETER
fh File handle (handle).
OUTPUT PARAMETERS
buf Initial address of buffer (choice).
status Status object (status).
IERROR Fortran only: Error status (integer).
DESCRIPTION
MPI_File_read_at_all_end is a split collective routine that stores the
number of elements actually read from the file associated with fh in
status. MPI_File_read_at_all_end blocks until the operation initiated
by MPI_File_read_at_all_begin completes. The data is taken out of 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
