what is "argc" and "argv[]" in systemc?

[Hook 1]

I don't know what is "argc" and "argv []" , Can you explain about this?And when does it change ?

#include "systemc.h"

int sc_main (int argc, char* argv[]) {
  cout<<"Value of argc="<<argc<<endl;
  cout <<"Value of argc[]="<<hex<<argc<<endl;
  return 0;
}

Hi,

These are the command line arguments argc and argv which are propagated from main(). See also https://stackoverflow.com/questions/3024197/what-does-int-argc-char-argv-mean#3024202

Doesn't make as much sense to those who use Windows and Visual Studio. Much more understandable if you use Linux.

Tip: You can access those two arguments from anywhere in your SystemC design using the two functions: sc_argc() and sc_argv(), which are in the sc_core namespace. Keep in mind that they only provide access to c_str values. If you want to interpret a numeric value from the command-line, you will need to convert it yourself.
