Is there a way to specify the command line as a stream in C? I realize that you can get command line parms from the main but since the code I am writing is an external procedure to Fortran code (specifically the NCAR graphics package. anyone that has already implemented this package and knows what procedure I am talking about would be able to help me greatly), I need a way to do it outside of the main code. Since I know input gets buffered, I am assuming that that buffer can be opened by specifying it in a stream. Am I wrong in this assumption? Any help would be greatly appreciated!!

It might have been invoked by a program calling system() or exec(). When it is called from the shell, the command line is buffered, but unfortunately it is not anywhere accessible to the program. It is buffered in the shell's process, but the command is run in a separate process. The best thing for you to do would be to have a pair of global variables, global_argc and global_argv, and have main() do global_argc = argc; global_argv = argv; Then you can refer to these from anywhere in your program.
