Constructor & Destructor Documentation

◆ FMallocDoubleFreeFinder()

FMallocDoubleFreeFinder::FMallocDoubleFreeFinder ( FMalloc * InMalloc )

Member Function Documentation

◆ Exec()

virtual bool FMallocDoubleFreeFinder::Exec	(	UWorld *	InWorld,
		const TCHAR *	Cmd,
		FOutputDevice &	Ar )

overridevirtual

Handles any commands passed in on the command line

Reimplemented from FExec.

◆ Init()

virtual void FMallocDoubleFreeFinder::Init ( )

virtual

Reimplemented from FMallocCallstackHandler.

◆ OverrideIfEnabled()

static FMalloc * FMallocDoubleFreeFinder::OverrideIfEnabled ( FMalloc * InUsedAlloc )

static

◆ TrackFree()

virtual void FMallocDoubleFreeFinder::TrackFree	(	void *	Ptr,
		uint32	OldSize,
		int32	CallStackIndex )

protectedvirtual

Implements FMallocCallstackHandler.

◆ TrackMalloc()

virtual void FMallocDoubleFreeFinder::TrackMalloc	(	void *	Ptr,
		uint32	Size,
		int32	CallStackIndex )

protectedvirtual

Implements FMallocCallstackHandler.

◆ TrackSpecial()

void FMallocDoubleFreeFinder::TrackSpecial ( void * Ptr )

If you get an allocation/memory error outside of the allocator you can call this directly It will dump a callstack of the last allocator free most likely to have caused the problem to the log, if you have symbols loaded Might be useful to pass an access violation ptr to this!
