Migrating your code to be void-safe is quite easy if you follow the recommendations presented in this document.
Prepare migration using EiffelStudio 6.3 or EiffelStudio 6.4 with the compatibility option
Compile your code using and apply the following refactorings:
- Search for callers of
{CELL}.default_createand replace it by callingputinstead and providing a sensible default value. - Search for callers of
{READABLE_STRING_8}.make_from_cand{READABLE_STRING_32}.make_from_c. If you are using them as part of a creation instruction or a creation expression then nothing to be done. Otherwise we recommend you to replace the call by a call tofrom_c. - Search for callers of
{C_STRING}.share_from_pointerand{C_STRING}.share_from_pointer_and_countand replace them bymake_shared_from_pointerandmake_shared_from_pointer_and_countwhen used as creation procedure, otherwise although it is ok to leave them as is, we recommend usingset_shared_from_pointerandset_shared_from_pointer_and_count.
