I have been optimising memory performance on a Windows Mobile application and have encountered some differences in behaviour between VirtualAlloc on Win32 and Windows CE. Consider the following test: // Allocate 64k of memory BYTE * a = (BYTE *)VirtualAlloc(0, 65536, MEM_RESERVE|MEM_COMMIT, PAGE_READWRITE); // Allocate a second contig...
