I am building a game, and I would like to run a function in the background.  While the user is playing the game, the user could type the [TAB] key to access a menu list where the user could save, load, quit, etc.  Also, while the user is playing the game, I would like to play a midi file in the background (Different function).  Simply put, when the user presses the [TAB] key on his/her keyboard, the program should run a certain function.  How would I accomplish this?

Natural way is: using threads.
About threads you can read in you Windows doc or see
 http://sourceware.cygnus.com/pthreads-win32/ for "pthreads"
If you want, i can send you simple example of using threads (write you EMail).

Why not? You (psevdo)code may be as :
#include <process.h>
void Thread1 (PVOID pvoid)
{
     while (!EndOfThread())
        {
          .....
        }
     _endthread () ;
}
void Thread2 (PVOID pvoid)
{
     while (!EndOfThread())
        {
          .....
        }
     _endthread () ;
}
void Thread3 (PVOID pvoid)
{
     while (!EndOfThread())
        {
          .....
        }
     _endthread () ;
}
void main()
{
   static PARAMS params1 ;
   static PARAMS params2 ;
   static PARAMS params3 ;
   _beginthread (Thread1, 0, &params1) ;
   _beginthread (Thread2, 0, &params2) ;
   _beginthread (Thread3, 0, &params3) ;
}
