C++ (Cpp) PREF_RegisterCallback Examples

Example #1

/* called from mkgeturl.c, NET_InitNetLib(). 
 * Initializes the pad variables and registers pad callbacks */
PUBLIC void
NET_RegisterPadPrefCallbacks(void) {
	XP_Bool x;
    char s[128];
    int len=sizeof(s);
	XP_MEMSET(s, 0, len);

	PREF_GetBoolPref(pref_enablePad, &x);
	MK_PadEnabled=x;
	PREF_RegisterCallback(pref_enablePad, net_EnablePadPrefChanged, NULL);

	PREF_GetCharPref(pref_padPacURL, s, &len);
	NET_SetPadPacURL(s);
	PREF_RegisterCallback(pref_padPacURL, net_PadPacURLPrefChanged, NULL);
}
