Detailed Description

'Name' provides a simple method to create numerical or more complex procedural names for entries and groups on the fly.

Example: prefs.set(Fl_Preferences::Name("File%d",i),file[i]);.

See test/preferences.cxx as a sample for writing arrays into preferences.

'Name' is actually implemented as a class inside Fl_Preferences. It casts into const char* and gets automatically destroyed after the enclosing call ends.
