I recommend asking questions like these on comp.lang.c; it's for
C-specific issues, not DJGPP specific ones.

You return multiple values from a C function in precisely the same way
you do it in Pascal; you pass pointers to the variables you want to
alter as arguments to the function and modify those values.  Pascal
refers to this as VAR passing; it has the same effect.  You can also
create a struct to hold the values and return that from the function.

Please read a good C textbook such as _The New C Primer Plus, 2nd
Edition_, by Waite & Del Prata, or Kernighan and Ritchie's _The C
Programming Language, 2nd Edition_.  Both are extraordinarily
well-written and will give you all the information you need.
