How about
			char *ptr, *getenv();
			ptr = getenv("HOME");

That would work on reasonably standard C compilers such as
MSC or Turbo C. It also works under UNIX.

On some compilers you need to pass **envptr as a third argument to
main(), and step through it like through **argv to find a string
starting with "HOME=", the remainder of the string would be the value.
I believe that the final pointer in the array **envptr is (char *)NULL.
