The simplest way is to write an _main function in assembler, linking it with the C runtime startup, and get argc, argv in the traditional manner. The other route would be to peruse the sources in /usr/src/lib/csu and see how the C runtime functions go about building the argument list for main. -- "Where am I, and what am I doing in this handbasket?"
