NAME

       MPI_File_read_all_end  -  Reads  a  file starting at the locations specified by individual
       file pointers; ending part of a split collective routine (blocking).

SYNTAX

C Syntax

       #include  <mpi.h>  int  MPI_File_read_all_end(MPI_File  fh,  void  *buf,        MPI_Status
       *status)

Fortran Syntax

       USE MPI
       ! or the older form: INCLUDE 'mpif.h'
       MPI_FILE_READ_ALL_END(FH, BUF, STATUS, IERROR)
            <type>    BUF(*)
            INTEGER   FH, STATUS(MPI_STATUS_SIZE), IERROR

C++ Syntax

       #include <mpi.h>
       void MPI::File::Read_all_end(void* buf, MPI::Status& status)

       void MPI::File::Read_all_end(void* buf)

INPUT/OUTPUT 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_all_end  is  the ending part of a split collective operation that stores the
       number of elements actually read  from  the  file  associated  with  fh  (at  the  current
       individual  file  pointer position maintained by the system) into the user's buffer buf in
       status.  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 Section 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++ 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.
