OK, regarding comments in this thread, you are completelly right. I am
fine with returning NULL.
BTW, should'nt this issue be commented in the standard? Perhaps in the
errata document? I think there is no a strong need to make it
MPI-2 could mandate/suggest that if size=0, the returned pointer is
NULL, but then MPI_Free_mem with a NULL pointer should succeed.
Now a question: What about Fortran ?
