- // TRACEFN is a macro that lets you generate indented TRACE output so you
- // can see the call stack. To use it:
- //
- // SomeFn(...)
- // {
- // TRACEFN("Entering SomeFn...n");
- // .
- // .
- // }
- //
- // Now all trace output after TRACEFN will be indented one space, until SomeFn
- // returns. You can put TRACEFN in multiple functions to see indented trace
- // output. For an example of this, see the HOOK sample program.
- //
- // NOTE: YOU MUST NOT USE TRACEFN IN A ONE-LINE IF STATEMENT!
- // This will fail:
- //
- // if (foo)
- // TRACEFN(...)
- //
- // Instead, you must enclose the TRACE in squiggle-brackets
- //
- // if (foo) {
- // TRACEFN(...)
- // }
- //
- #define TRACEFN CTraceFn __fooble; TRACE
- //
- // This class implements TRACEFN. Don't ever use directly!
