Hi, Scrutinizer:

Your interpretation is indeed correct, but its correctness hinges on export always returning 0. I mentioned that not to nitpick, but as a heads up for newbies.

Regards,
Alister

MPI_Sizeof(3)							     Open MPI							     MPI_Sizeof(3)

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 intrinsic 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++ 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. 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. 1.4.5 Feb 10, 2012 MPI_Sizeof(3)
