As requested, here is the code that is failing:
MakeString takes a CFStringRef and returns a std::string used for logging
GetUrlPath takes a CFURLRef and returns a std::string used for logging
CFURLRef bundleUrl =
CFURLCreateCopyAppendingPathComponent(kCFAllocatorDefault, appURL,
m_bundles[loop].m_bundleName, true);
ASSERT(bundleUrl);
m_bundles[loop].m_bundle = CFBundleCreate(kCFAllocatorDefault, bundleUrl);
ASSERT(m_bundles[loop].m_bundle);
CFURLRef checkURL = CFBundleCopyBundleURL(m_bundles[loop].m_bundle);
TRACE("checkURL=%s\n", GetUrlPath(checkURL).c_str());
if (m_bundles[loop].m_functionNames)
{
for (size_t func = 0; m_bundles[loop].m_functionNames[func]; func++)
{
TRACE("Loading function %s\n",
MakeString(m_bundles[loop].m_functionNames[func]).c_str());
void* ptr =
CFBundleGetFunctionPointerForName(m_bundles[loop].m_bundle,
m_bundles[loop].m_functionNames[func]);
ASSERT(ptr);
if (ptr)
{
m_functionMap.insert(FunctionMap::value_type(m_bundles[loop].m_functionNames
[func], ptr));
}
}
}
CFRelease(bundleUrl);
And here are some of the function names
CFStringRef AssignFontTable = CFSTR("_AssignFontTable");
CFStringRef GetSuperset = CFSTR("_GetSuperset");
CFStringRef StoreSuperset = CFSTR("_StoreSuperset");
CFStringRef DecryptSuperset = CFSTR("_DecryptSuperset");
CFStringRef EncryptSuperset = CFSTR("_EncryptSuperset");
