It doesn't seem to make sense, unless we just ignore any potential excess space at the beginning of a segment, and then have the first allocated chunk be at the first multiple of 8 (with its corresponding first header being that address -4). This would leave however many bytes before that unused. Is that what's generally done?

What alignment does HeapAlloc use

I'm developing a general purpose library which uses Win32's HeapAlloc MSDN doesn't mention alignment guarantees for Win32's HeapAlloc, but I really need to know what alignment it uses, so I can avoid excessive padding. On my machine (vista, x86), all allocations are aligned at 8 bytes. Is this… >>> More

Hi, I'm having code that, for various reasons, I'm trying to port from the C runtime to one that uses the Windows Heap API. I've encountered a problem: If I redirect the malloc/calloc/realloc/free calls to HeapAlloc/HeapReAlloc/HeapFree (with GetProcessHeap for the handle), the memory seems to be… >>> More

Hi, In Windows, for very demanding applications, a programmer may use HeapCreate, HeapAlloc in order to better manage and control the allocation of memory- speed it up (aka private allocators). What is the equivalent in Linux c++ programming? >>> More

Where are some good resources for looking at the pros/cons of different ways of implementing heap allocators? Resources touching on efficiency (fragmentation, throughput, etc) are preferred. I am NOT looking for simple code repositories. >>> More
