Re: Help- selective symbol exposure after link

NT DLLs require subsequent code to do something special to access
imported static data (sort of analogous to the jump table used for code
imports).


OS/2 DLLs are an order better and allow code and data to be exported
without penalty (again with tight visibility control including ordinal
reference as well as symbolic reference).


ELF shared-objects are however rather more primitive (and require to be
compiled PIC, yeuch!) but can do similar service - I believe gcc under
linux can control which symbols are exported when a shared-object is
bound.
