-
- It is possible to combine several of the proposed solutions to
- run time lookup of symbolic constants. For example, one might
- do the following to establish the values V1 ... Vn as defined
- in file H.h:
-
- 1) Attempt the cc -E lookup in H.h.
- 2) If any (or all) values remain undefined, try the table lookup
- in /etc/H.
- 3) If the user has specified environment variable H-Vi, use that
- instead of any lookup value.
- 4) Return the values.
-
- Shuffle the precedence as you see fit. You can arrange for /etc/H to
- override the values in H.h. You can ignore what's in the environment.
- Perhaps we can agree on what makes the most sense, and then somebody
- can crank out a routine for public use.
