#pragma once
//
// 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"));
//
