If I were you, I'd do something like (warning: Mail compiled code):
const char* MyGetLocalizedCString(CFStringRef string)
{
// if you need to be thread safe, add proper locks around that
static CFMutableDictionaryRef mapping = NULL;
if(mapping == NULL) {
mapping = CFDictionaryCreateMutable(NULL, 0,
&kCFTypeDictionaryKeyCallBacks, NULL);
}
const char* result = (const char *)CFDictionaryGetValue(mapping,
string);
if(result == NULL) {
CFStringRef localizedString =
CFCopyLocalizedStringFromTable(string,
CFSTR("LibraryLocalizable"), NULL);
result = (const char
*)malloc(CFStringGetMaximumSizeForEncoding(CFStringGetLength(localize
dString),
kCFStringEncodingUTF8);
CFStringGetCString(localizedString, (char *)result, bufferSize,
kCFStringEncodingUTF8);
CFDictionarySetValue(mapping, string, result);
I'm not sure CFDictionarySetValue would accept a char *.
It accepts whatever you want. You just have to set the corresponding
callback when you create it. As you can see here, this sample use NULL
as Value CallBack, so it perfectly valid to set a char *.
You're right. It just seems strange from a memory management point of
view.
