MPI_File_read_all_end(3OpenMPI) 										   MPI_File_read_all_end(3OpenMPI)

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
	   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++ 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.
