Hi folks,

3. Deprecate MPI_SIZEOF ... Bill: implementation of storage_size() is pretty trivial JeffH: there's also c_sizeof() (Bill says this is F03)

Actually C_SIZEOF like STORAGE_SIZE was added in F2008; it does not appear in F2003.

Bill: c_sizeof() uses C rules -- e.g., you get size of total array, etc. (returns answer in bytes, not bits).

Yes, but it only works for "interoperable" objects... so not on Fortran derived types that do not have the BIND attribute. Some compilers might do C_SIZEOF on anything, but it is certainly not in the standard. So STORAGE_SIZE(thingo)/STORAGE_SIZE(byte) would seem to be the recommended formulation, multiplied by SIZE(thingo) if it is an array and you want the total size of the array.
