I have this from another thread - https://groups.google.com/g/fltkgeneral/c/QnCEjdgiIPc/m/DCilrsHVAgAJ
ATM, I am using this. Just wondering if there is an API call I am missing.
void copyGroup_(Fl_Preferences& src, Fl_Preferences& dst)
{
for (int i = 0; i < src.groups(); ++i) {
Fl_Preferences s(src, i);
Fl_Preferences d(dst, s.name());
copyGroup_(s, d);
}
for (int i = 0; i < src.entries(); ++i) {
const char* name = src.entry(i);
char* data;
src.get(name, data, "");
dst.set(name, data);
::free(data);
}
}
copyPrefs() { Fl_Preferences srcFile(Fl_Preferences::USER, "fltk.org", "Hello"); Fl_Preferences dstFile("/Users/matt/test.cfg", "matthiasm.com", "export"); copyGroup_(srcFile, dstFile); }

As we know, prefsP_ is written to HDD. dataP_ is only maintained in memory. In my code design, I'd like to make an identical copy of prefsP_ as runtime. The user can access these values without disk access and modify them as needed.
Only values that need to be saved will be written to HDD via prefsP_
Is there an API call like - copy (prefsP_, dataP_) or something similar ?
