If I recall correctly the rrd_* functions parse the input with getopt and if you give options on the command line the argv array is NULL terminated at argv[argc]. Another pitfall is caused by the fact that getopt uses the optind variable and this variable is global ! So you have to reset optind before each call to rrd_*() It's a simple optind=0 but its annoying... Hope this helps...Andreas. P.S.: Hmmm... Maybe I will write a small documentation of the rrdtool-API. -- Dipl.-Ing.
