Question

I have a piece of C++ code that calls the system command.. I want to pass the file name of my own C++ executable to the system command.. anyone know how to do this?
So for example my C++ code is called “switch-5”.. what I want to do is something like;

system(“./script.sh switch-5”);

Anyone have any clue?

Answer 1

Your executable name is the first argument passed in argv.

To test this just run:

int main(int argc, char **argv)
{
   printf("My program name: '%s'\n", argv[0]);
   return 0;
}

(I am assuming you know how to combine it with your script name to get the string to pass to system().)
