Detailed Description

Collection of debugging macros.

This file contains a collection of debugging macros. It is intended to be included in C source files only, not in C header files.

The macros ERRMSG() and BUG() are available by simply including this header file. The macros ASSERT(), COND(), and ERRCOND() provide assertion checking that is enabled by defining either DEBUG_SUPPORT or DEBUG_WATCH. Defining DEBUG_WATCH permits the expansion of macros TEXT(), STR(), INT(), PTR(), FLT(), and VEC() that displays quantities. A non-externally linked global integer variable DEBUG_COUNTER is also enabled by defining DEBUG_WATCH. The DEBUG_COUNTER variable is automatically incremented by each of the "watch" macros. It can be useful in the context of debugging loops.
