MPI_Sizeof(3OpenMPI)                                                                    MPI_Sizeof(3OpenMPI)



NAME
       MPI_Sizeof - Returns the size, in bytes, of the given type


SYNTAX
Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_SIZEOF(X, SIZE, IERROR)
       <type>    X
       INTEGER   SIZE, IERROR


INPUT PARAMETER
       X         A Fortran variable of numeric intrisic type (choice).


OUTPUT PARAMETERS
       SIZE      Size of machine representation of that type (integer).

       IERROR    Error status (integer).


DESCRIPTION
       MPI_SIZEOF  returns  the size (in bytes) of the machine representation of the given variable. It is a
       generic Fortran type and has a Fortran binding only. This routine is similar to the sizeof builtin in
       C/C++.  However, if given an array argument, it returns the size of the base element, not the size of
       the whole array.


NOTES
       This function is not available in C/C++ because it is not necessary.


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. By default, this error
       handler aborts the MPI job, except for I/O function errors. The error handler  may  be  changed  with
       MPI_Comm_set_errhandler;  the  predefined  error handler MPI_ERRORS_RETURN may be used to cause error
       values to be returned. Note that MPI does not guarantee that an MPI  program  can  continue  past  an
       error.

       See the MPI man page for a full list of MPI error codes.
