MPI_Type_get_contents(3)					      LAM/MPI						  MPI_Type_get_contents(3)

NAME

       MPI_Type_get_contents -	Get datatype contents

SYNOPSIS

       #include <mpi.h>
       int
       MPI_Type_get_contents(MPI_Datatype type, int nints, int naddrs,
	       int ndtypes, int *ints, MPI_Aint *addrs,
	       MPI_Datatype *dtypes)

INPUT PARAMETER

       type   - Datatype to access
       nints  - Number of elements in ints
       naddrs - Number of elments in addrs
       ndtypes
	      - Number of elements in dtypes

OUTPUT PARAMETERS

       ints   - Contains integer arguments used in constructing datatype
       addrs  - Contains address arguments used in constructing datatype
       dtypes - Contains datatype arguments used in constructing datatype

NOTES FOR FORTRAN

       All  MPI  routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument list.  ierr
       is an integer and has the same meaning as the return value of the routine in C.	In Fortran, MPI routines are subroutines, and are  invoked
       with the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.

ERRORS

       If an error occurs in an MPI function, the current MPI error handler is called to handle it.  By default, this error handler aborts the MPI
       job.  The error handler may be changed with MPI_Errhandler_set ; the predefined error handler MPI_ERRORS_RETURN may be used to cause  error
       values  to  be  returned  (in  C and Fortran; this error handler is less useful in with the C++ MPI bindings.  The predefined error handler
       MPI::ERRORS_THROW_EXCEPTIONS should be used in C++ if the error value needs to be recovered).  Note that MPI does not guarantee that an MPI
       program can continue past an error.

       All  MPI  routines (except MPI_Wtime and MPI_Wtick ) return an error value; C routines as the value of the function and Fortran routines in
       the last argument.  The C++ bindings for MPI do not return error values; instead, error values are communicated by throwing  exceptions	of
       type MPI::Exception (but not by default).  Exceptions are only thrown if the error value is not MPI::SUCCESS
	.

       Note  that  if the MPI::ERRORS_RETURN handler is set in C++, while MPI functions will return upon an error, there will be no way to recover
       what the actual error value was.
       MPI_SUCCESS
	      - No error; MPI routine completed successfully.
       MPI_ERR_ARG
	      - Invalid argument.  Some argument is invalid and is not identified by a specific error class.  This is typically a NULL pointer	or
	      other such error.
       MPI_ERR_TYPE
	      - Invalid datatype argument.  May be an uncommitted MPI_Datatype (see MPI_Type_commit ).

       documents contain detailed information about each MPI function (most of which is not duplicated in these man pages).
