MPI_File_write_at_all_end(3OpenMPI)									       MPI_File_write_at_all_end(3OpenMPI)

NAME

       MPI_File_write_at_all_end - Writes a file at explicitly specified offsets; ending part of a split collective routine (blocking).

SYNTAX

       C Syntax
	   #include <mpi.h>
	   int MPI_File_write_at_all_end(MPI_File fh, 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).

DESCRIPTION

       MPI_File_write_at_all_end  is  the  ending  part of a split collective routine 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 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.

NAME

       MPI_File_read_shared - Reads a file using the shared file pointer (blocking, noncollective).

SYNTAX

       C Syntax
	   #include <mpi.h>
	   int MPI_File_read_shared(MPI_File fh, void *buf, int count,
       MPI_Datatype datatype, MPI_Status *status)

       Fortran Syntax
	   INCLUDE 'mpif.h'
	   MPI_FILE_READ_SHARED(FH, BUF, COUNT, DATATYPE, STATUS,
	    IERROR)
		 <TYPE> 	BUF(*)
		 INTEGER	FH, COUNT, DATATYPE,
			   STATUS(MPI_STATUS_SIZE), IERROR

C++ Syntax
       #include <mpi.h>
       void MPI::File::Read_shared(void* buf, int count,
	    const MPI::Datatype& datatype, MPI::Status& status)

       void MPI::File::Read_shared(void* buf, int count,
	    const MPI::Datatype& datatype)

INPUT
/OUTPUT PARAMETER
       fh	 File handle (handle).

INPUT PARAMETERS

       count	 Number of elements in buffer (integer)

       datatype  Data type of each buffer element (handle).

OUTPUT PARAMETERS

       buf	 Initial address of buffer (choice).

       status	 Status object (status).

       IERROR	 Fortran only: Error status (integer).

DESCRIPTION

       MPI_File_read_shared is a blocking routine that uses the shared file pointer to read files. The order of serialization is not deterministic
       for this noncollective routine.

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.
