I don't see anything obviously wrong, but I'd bet a bug related to 32/64-bit types. Can you post a complete piece of code that can be compiled and run and demonstrates the problem? Also, try compiling with -Wall -W and investigate any warnings that are produced. By the way, errno 22 is EINVAL, "Invalid argument". perror() is your friend.
