The code around the call in the app:
VirtualQuery(shm_ptr, &shm_info, sizeof(MEMORY_BASIC_INFORMATION));
if ( ( shm_info.RegionSize < shmTotalSize ) || ( shm_info.State != MEM_FREE ))
{
errno = GetLastError();
CR_ERRNOMSG("VirtualQuery");
crWto(UL041E, ipcKey, shm_ptr, 0);
CR_RETVAL(NULL);
}
I don't really know whats in the shm_info structur... but I'll see if I can build some debugging messages into it and try again. Lotsa work :(
