MPI_Get_elements(3)							MPI						       MPI_Get_elements(3)

NAME

       MPI_Get_elements -  Returns the number of basic elements in a datatype

SYNOPSIS

       int MPI_Get_elements(MPI_Status *status, MPI_Datatype datatype, int *elements)

INPUT PARAMETERS

       status - return status of receive operation (Status)
       datatype
	      - datatype used by receive operation (handle)

OUTPUT PARAMETER

       count  - number of received basic elements (integer)

NOTES

       If  the size of the datatype is zero and the amount of data returned as determined by status is also zero, this routine will return a count
       of zero.  This is consistent with a clarification made by the MPI Forum.

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

       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.  Before the value is returned, the current MPI error handler is called.  By default, this error handler aborts the MPI
       job.  The error handler may  be	changed  with  MPI_Comm_set_errhandler	(for  communicators),  MPI_File_set_errhandler	(for  files),  and
       MPI_Win_set_errhandler  (for  RMA  windows).   The  MPI-1 routine MPI_Errhandler_set may be used but its use is deprecated.  The predefined
       error handler MPI_ERRORS_RETURN may be used to cause error values to be returned.  Note that MPI does not guarentee that an MPI program can
       continue past an error; however, MPI implementations will attempt to continue whenever possible.

       MPI_SUCCESS
	      - No error; MPI routine completed successfully.
