This is normally handled by setting application preferences for each
application.
Are you using CodeWarrior? Starter.c and Starter.cpp both contain the
outline of how you do this:
typedef struct
{
// put your variables here
UInt8 replaceme;
} StarterPreferenceType;
...
#define appPrefID 0x00
#define appPrefVersionNum 0x01
...
static Err AppStart(void)
{
StarterPreferenceType prefs;
UInt16 prefsSize;
// Read the saved preferences / saved-state information.
prefsSize = sizeof(StarterPreferenceType);
if (PrefGetAppPreferences(appFileCreator, appPrefID, &prefs, &prefsSize,
true) !=
noPreferenceFound)
{
// save prefs info in some global vars
}
return errNone;
}
static void AppStop(void)
{
StarterPreferenceType prefs;
// Write the saved preferences / saved-state information.
PrefSetAppPreferences (appFileCreator, appPrefID, appPrefVersionNum,
&prefs, sizeof (prefs), true);
// Close all the open forms.
FrmCloseAllForms ();
}
