Hm, I wrote a little C a few years ago utility that prints a date-time prefix and the raw command line string but skipping arg 0. It uses win32's GetCommandLine, which returns a string pointer. [18:58] C:\pywk\clp>logline arg1 arg2 note preserved spaces. 20051110 18:58:24 arg1 arg2 note preserved spaces. Maybe ctypes could be used to get the pointer and carefully poke in a mod. But I don't know if the cmd line string is within a static fixed size array so you could lengthen it, or what. Or have they opened the source for that? Anyway, I don't know if that is where ps (pstat on my NT box) looks. Not handy to experiment ATM ;-) Regards, Bengt Richter -- http://mail.python.org/mailman/listinfo/python-list
