I am wondering if there is a way to (much like exporting in Linux) set an
environmental variable via  putenv(); function and export this variable so
when the program has terminated that the variable will still be a part of
the msdos environmental variables.  Allow me to give a short example..   Say
I wanted to do something like so.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

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

 // Environmental String Variables
 char user[100];
 char name[100];

 printf("Username: ");
 scanf("%s",user);

 sprintf(name,"set user=%s",user);
 putenv(name);
 return 0;
 }

Now of course when this program terminates the variable for user is not
going to still be set.  If anyone understands what I am talking about...  I
am wanting a way other than possibly reading a cfg file to set this and have
it become an environmental variable at least until the PC has been restarted
or the variable has been changed.

Any ideas?

Mrs. Amber Nicole Stange
