Thanks for the link, but that doesn't explain the usage.

As I read it, the FindTable declaration means that the data-structure pointed to is read-only, and that the pointer value itself is also read-only. But making a pointer value read-only is something only useful to the internals of a method, and should make no difference to the API signature.

Hi

I'm seeing declarations like this scattered around the SW module:
e.g. in sw/inc/swtable.hxx at line 301

  static SwTable * FindTable( SwFrmFmt const*const pFmt );

As far as I can tell from my limited C++ knowledge, this is the same as the
more common definition:

  static SwTable * FindTable( const SwFrmFmt * pFmt );

i.e. the second const serves no purpose - or am I missing something?
You are missing something :)
