// These macros are used for debugging purposes. They expand
// to white spaces on a free build. Here is a brief description
// of what they do and how they are used:
//
// giDebugLevel
//  Global variable which set the current debug level to control
//  the amount of debug messages emitted.
//
// VERBOSE(msg)
//  Display a message if the current debug level is <= DBG_VERBOSE.
//
// TERSE(msg)
//  Display a message if the current debug level is <= DBG_TERSE.
//
// WARNING(msg)
//  Display a message if the current debug level is <= DBG_WARNING.
//  The message format is: WRN filename (linenumber): message
//
// ERR(msg)
//  Similiar to WARNING macro above - displays a message
//  if the current debug level is <= DBG_ERROR.
//
// ASSERT(cond)
//  Verify a condition is true. If not, force a breakpoint.
//
// ASSERTMSG(cond, msg)
//  Verify a condition is true. If not, display a message and
//  force a breakpoint.
//
// RIP(msg)
//  Display a message and force a breakpoint.
//
// Usage:
//  These macros require extra parantheses for the msg argument
//  example, ASSERTMSG(x > 0, ("x is less than 0\n"));
//           WARNING(("App passed NULL pointer, ignoring...\n"));

// To use these macros in a file, here is what you should do:
//
// At the beginning of the file (after header includes):
//
//  Define a bit constant for each function you want to trace
//  Add the following line
//      DEFINE_FUNCTION_TRACE_FLAGS(flags);
//  where flags is a bit-wise OR of the functions you want to trace, e.g.
//      TRACE_FLAG_FUNC1 | TRACE_FLAG_FUNC2 | ...
//
//  To generate trace inside each function you want to trace, use:
//      FUNCTION_TRACE(FunctionTraceFlag, (args));
