Member Function Documentation

◆ Free()

void FTraceMalloc::Free ( void *  Original)
overridevirtual

Free

Implements FMalloc.

◆ Malloc()

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

Malloc

Implements FMalloc.

◆ OnMallocInitialized()

virtual void FTraceMalloc::OnMallocInitialized ( )
inlineoverridevirtual

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

Reimplemented from FMalloc.

◆ OnPostFork()

virtual void FTraceMalloc::OnPostFork ( )
inlineoverridevirtual

Notifies the malloc implementation that the process has forked so we can try and avoid dirtying pre-fork pages.

Reimplemented from FMalloc.

◆ OnPreFork()

virtual void FTraceMalloc::OnPreFork ( )
inlineoverridevirtual

Notifies the malloc implementation that the process is about to fork. May be used to trim caches etc.

Reimplemented from FMalloc.

◆ Realloc()

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

Realloc

Implements FMalloc.
