Such as mutexes, semaphores, etc. There's a complete chapter about
'Synchronization' in MSDN:

Sure you can. And if I recall correctly, CreateFileMapping can be used
to allocate and use directly _memory_ instead of files (using
(HANDLE)0xFFFFFFFF as first parameter). My suggestion is to use a
struct (let's call it StructSharedData) with all the data you need:

struct StructSharedData
    {
    int whatever;
    } *SD;

HANDLE hSD;
hSD = CreateFileMapping((HANDLE)0xFFFFFFFF, NULL, PAGE_READWRITE, 0,
sizeof(*SD), "SD");
SD = (StructSharedData *)MapViewOfFile(hSD, FILE_MAP_WRITE, 0, 0,
sizeof(*SD));
...
Use SD as needed...
...
UnmapViewOfFile(SD);
CloseHandle(hSD);
