It sets up an exception handler, which calls RtlUnwind(), which is usually generated by the compiler for try/except. It then moves to allocate space on the heap using HeapCreate() called by __bheapinit(). If failed, then exit. Otherwise, system setting up continues........

TITLE : Developer Library » Memory Fragmentation, your worst nightmare
Rather than just use malloc, new etc to allocate in the C runtime heap you could choose to do all allocations for specific objects in a specific heap created by using HeapCreate(); This is useful because it forces all allocations of a specific size and type into one heap. Thus the allocation behaviour that was causing fragmentation in one heap is now split among many heaps and may not cause fragmentation when split like that........

TITLE : Heap Overflow: Vulnerability and Heap Internals Explained
The dynamic heap is created by functions such as HeapCreate() that return a handle/address to a memory chunk that contains the heap header; the information in this header includes the segment table, virtual allocation list, free list usage bitmap, free list table, lookaside table, etc. This data is used by heap allocation functions such as HeapAlloc(), HeapReAlloc(), which allocates memory from this particular heap........

Thanks for the reply, if the third parameter is 0, so the size of the heap can grow itself when needed, right? What if I define, HeapCreate( 0, 2 * 1024, 2 * 1024), does this mean the heap has a fixed size 2 * 1024? Thanks. ? satellite Jan 18 '13 at 20:14.......

TITLE : c++ - malloc() vs. HeapAlloc() - Stack Overflow
With Visual C++, the function malloc() or the operator new eventually calls HeapAlloc(). If you debug the code, you will find the the function _heap_alloc_base() (in the file malloc.c) is calling return HeapAlloc(_crtheap, 0, size) where _crtheap is a global heap created with HeapCreate()........
