Access command line arguments without using char **argv in main

Question

Is there any way to access the command line arguments, without using the argument to main? I need to access it in another function, and I would prefer not passing it in.

I need a solution that only necessarily works on Mac OS and Linux with GCC.

In Linux, you can open /proc/self/cmdline (assuming that /proc is present) and parse manually (this is only required if you need argc/argv before main() - e.g. in a global constructor - as otherwise it's better to pass them via global vars).

Yeah, it's gross and unportable, but if you are solving practical problems you may not care.
