how can port code windows c++ using alternative function?

thanks

if had searched have found thread goes on compatibility libraries getopt, among other implementations, windows based systems.

getopt.h: compiling linux c-code in windows

on note, use va_arg, va_list, va_start, , va_end functions process arguments well.

/* va_arg example */ #include <stdio.h>      /* printf */ #include <stdarg.h>     /* va_list, va_start, va_arg, va_end */  int findmax (int n, ...) {   int i,val,largest;   va_list vl;   va_start(vl,n);   largest=va_arg(vl,int);   (i=1;i<n;i++)   {     val=va_arg(vl,int);     largest=(largest>val)?largest:val;   }   va_end(vl);   return largest; }  int main () {   int m;   m= findmax (7,702,422,631,834,892,104,772);   printf ("the largest value is: %d\n",m);   return 0; }
