hi Gerry.. you may be interested in the following functions: int copyin(const void *uaddr, void *kaddr, size_t len); int copyout(const void *kaddr, void *uaddr, size_t len); int copyinstr(const void *uaddr, void *kaddr, size_t len, size_t *done); int bcopy(const void *src, const void *dst, len);
this functions are using for syscalls related work, among other things..lucky!!
