[Swig-user] No need to modifiy the original C-file? Variable input paramater?

[<ka...@ar...>]

Hello,

I've a short question if I do understand http://swig.org/Doc1.3/Lua.html correctly:

If I use swig, I will not need modify my c-program? only create an additional file / swig module *i .
which contains variable input parameters?

But what do I need to do, if don't have a so clear structure such as "int gcd(int x, int y);"

because in my problem, I've something like that


main (int argc, char *argv[])
{
...
}

Of course in the program there are various code for handling the commandline arguments....

The command and the argument argument at the console looks like:

myproc -input ','tmp',' -format ','float',' -output ','tmp_out',' -xsize ',100

Thanks in advance

Mariol
