- IMPORTANT NOTES ABOUT THE C CONVERSION
- --------------------------------------
-
- o Pascal "var" parameters are converted from "var x : y" to "y *x". This
- means that when you see the parameter "y *x" you should be aware that
- you *cannot pass in nil*. In future this restriction may be eased,
- especially for the attr parameter to ICGetPref. Parameters where nil
- is legal are declared using the explicit pointer type, ie "yPtr x".
-
- o Strings are *Pascal* strings. This means that they must be word aligned.
- MPW and Think C do this automatically. The last time I check, Metrowerks
- C does not. If it still doesn't, then IMHO it's a bug in their compiler
- and you should report it to them.
-
- o The canonical Internet Config interface is defined in Pascal. These
- headers have not been thoroughly tested. If there is a conflict between
- these headers and the Pascal interfaces, the Pascal should take precedence.
