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_create
and replace it by callingput
instead and providing a sensible default value. - Search for callers of
{STRING_8}.make_from_c
and{STRING_32}.make_from_c
. Replace them bymake_from_c_pointer
when used as creation procedure, otherwise it is ok to leave it as is. - Search for callers of
{C_STRING}.share_from_pointer
and{C_STRING}.share_from_pointer_and_count
and replace them bymake_shared_from_pointer
andmake_shared_from_pointer_and_count
when used as creation procedure, otherwise although it is ok to leave them as is, we recommend usingset_shared_from_pointer
andset_shared_from_pointer_and_count
.
