Thanks, What I learned was if flag contain O_CREAT, you should be supplying a mode argument (I also learned that I should read man pages more carefully :). Otherwise mode gets some garbage. What confused me was Linux man pages, Solaris man page gives the declaration as open(char *path, int flags, ...)
