class FMallocThreadSafeProxy : public FMalloc

FMalloc proxy that synchronizes access, making the used malloc thread safe.

	Type	Name	Description
		FMallocThreadSafeProxy ( FMalloc* InMalloc )	Constructor for thread safe proxy malloc that takes a malloc to be used and a synchronization object used via FScopeLock as a parameter.

Type	Name	Description
void	DumpAllocatorStats ( FOutputDevice& Ar )	Dumps allocator stats to an output device.
void	Free ( void* Ptr )	Free
bool	GetAllocationSize ( void* Original, SIZE_T& SizeOut )	If possible determine the size of the memory allocated at the given address
void	GetAllocatorStats ( FGenericMemoryStats& out_Stats )	Writes allocator stats from the last update into the specified destination.
const TCHAR *	GetDescriptiveName ()	Gets descriptive name for logging purposes.
void	InitializeStatsMetadata ()	Initializes stats metadata.
bool	IsInternallyThreadSafe ()	Returns if the allocator is guaranteed to be thread-safe and therefore doesn't need a unnecessary thread-safety wrapper around it.
void *	Malloc ( SIZE_T Size, uint32 Alignment )	Malloc
void	OnMallocInitialized ()	Notifies the malloc implementation that initialization of all allocators in GMalloc is complete, so it's safe to initialize any extra features that require "regular" allocations
void	OnPostFork ()	Notifies the malloc implementation that the process has forked so we can try and avoid dirtying pre-fork pages.
void	OnPreFork ()	Notifies the malloc implementation that the process is about to fork.
void *	Realloc ( void* Ptr, SIZE_T NewSize, uint32 Alignment )	Realloc
void	Trim ( bool bTrimThreadCaches )	Releases as much memory as possible. Must be called from the main thread.
bool	ValidateHeap ()	Validates the allocator's heap
