关键代码:WindowsPlatformMisc.cpp中PureCallHandler这个函数
HoloLensMisc.cpp中也包含了PureCallHandler这个静态函数
extern CORE_API bool GEdSelectionLock;
extern CORE_API bool GIsClient;
extern CORE_API bool GIsServer;
extern CORE_API bool GIsCriticalError;
extern CORE_API TSAN_ATOMIC(bool) GIsRunning;
extern CORE_API bool GIsDuplicatingClassForReinstancing;
if( GIsRunning )
{
FMessageDialog::Open( EAppMsgType::Ok, NSLOCTEXT("Core", "PureVirtualFunctionCalledWhileRunningApp", "Pure virtual function being called while application was running (GIsRunning == 1).") );
}
static void PureCallHandler()
{
static bool bHasAlreadyBeenCalled = false;
UE_DEBUG_BREAK();
if (bHasAlreadyBeenCalled)
{
// Call system handler if we're double faulting.
if (DefaultPureCallHandler)
{
DefaultPureCallHandler();
}
}
else
{
bHasAlreadyBeenCalled = true;
if (GIsRunning)
{
FMessageDialog::Open(EAppMsgType::Ok, NSLOCTEXT("Core", "PureVirtualFunctionCalledWhileRunningApp", "Pure virtual function being called while application was running (GIsRunning == 1)."));
}
UE_LOG(LogTemp, Fatal, TEXT("Pure virtual function being called"));
}
}
static void PureCallHandler()
{

UE_DEBUG_BREAK();
if( bHasAlreadyBeenCalled )
