Overridden from FMalloc

  Type Name Description
Public function Virtual void

Free ( void* Original
)

 Free
Public function Virtual bool

GetAllocationSize ( void* Original,
SIZE_T& SizeOut
)

 If possible determine the size of the memory allocated at the given address
Public function Virtual const TCHAR * Gets descriptive name for logging purposes.
Public function Virtual Const bool Returns if the allocator is guaranteed to be thread-safe and therefore doesn't need a unnecessary thread-safety wrapper around it.
Public function Virtual void *

Malloc ( SIZE_T Count,
uint32 Alignment
)

 Malloc
Public function Virtual void *

Realloc ( void* Original,
SIZE_T Count,
uint32 Alignment
)

 Realloc
Public function Virtual void *

TryMalloc ( SIZE_T Count,
uint32 Alignment
)

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

TryRealloc ( void* Original,
SIZE_T Count,
uint32 Alignment
)

 TryRealloc - like Realloc(), but may return a nullptr if the allocation request cannot be satisfied.
Public function Virtual bool Validates the allocator's heap
