Get command line via system calls?

["Michael D. Crawford" <crawford@goingware.com>]

Can one get a program's command line parameters via system or library calls?

I'm looking for a *portable* way to get the command line in a FORTRAN 77 
program.  That version of FORTRAN didn't provide command line parameters 
in a portable way.  One can get them, but the code required is not 
portable between compilers.  Each environment provides a different way.

The obvious solution would be for me to start the program in C code, so 
I could get the argc and argv parameters to main, but I'd like to know 
if there is some way I can get them without changing my program's entry 
point.

I looked around in the man pages, and found the getenv function, which 
fetches the environment, but I didn't see anything about getting command 
line parameters the way I'm thinking of.

Thanks for your help!
