Constructor & Destructor Documentation

◆ FMallocAnsi()

FMallocAnsi::FMallocAnsi ( )

Constructor enabling low fragmentation heap on platforms supporting it.

Member Function Documentation

◆ Free()

virtual void FMallocAnsi::Free ( void * Original)
overridevirtual

Free

Implements FMalloc.

◆ GetAllocationSize()

virtual bool FMallocAnsi::GetAllocationSize ( void * Original,
SIZE_T & SizeOut )
overridevirtual

If possible determine the size of the memory allocated at the given address

Parameters
Original- Pointer to memory we are checking the size of
SizeOut- If possible, this value is set to the size of the passed in pointer
Returns
true if succeeded

Reimplemented from FMalloc.

◆ GetDescriptiveName()

virtual const TCHAR * FMallocAnsi::GetDescriptiveName ( )
inlineoverridevirtual

Gets descriptive name for logging purposes.

Returns
pointer to human-readable malloc name

Reimplemented from FMalloc.

Definition at line 52 of file MallocAnsi.h.

◆ IsInternallyThreadSafe()

virtual bool FMallocAnsi::IsInternallyThreadSafe ( ) const
overridevirtual

Returns if the allocator is guaranteed to be thread-safe and therefore doesn't need a unnecessary thread-safety wrapper around it.

Returns
true as we're using system allocator

Reimplemented from FMalloc.

◆ Malloc()

virtual void * FMallocAnsi::Malloc ( SIZE_T Count,
uint32 Alignment )
overridevirtual

Malloc

Implements FMalloc.

◆ Realloc()

virtual void * FMallocAnsi::Realloc ( void * Original,
SIZE_T Count,
uint32 Alignment )
overridevirtual

Realloc

Implements FMalloc.

◆ TryMalloc()

virtual void * FMallocAnsi::TryMalloc ( SIZE_T Count,
uint32 Alignment )
overridevirtual

TryMalloc - like Malloc(), but may return a nullptr result if the allocation request cannot be satisfied.

Reimplemented from FMalloc.

◆ TryRealloc()

virtual void * FMallocAnsi::TryRealloc ( void * Original,
SIZE_T Count,
uint32 Alignment )
overridevirtual

TryRealloc - like Realloc(), but may return a nullptr if the allocation request cannot be satisfied. Note that in this case the memory pointed to by Original will still be valid

Reimplemented from FMalloc.

◆ ValidateHeap()

virtual bool FMallocAnsi::ValidateHeap ( )
overridevirtual

Validates the allocator's heap

Reimplemented from FMalloc.
