+//  cegclient.h
+//
+//	This file is to be imported by client applications that wish to link with our DRM library !
+//	
+//	Performance Note : 
+//
+//	There are several points within cegclient.h where we'll place a 'Performance Note' to indicate
+//	the potential performance consequences of particular CEG functions.
+//
+//	
+//
+//
+//	CEG Initialization - 
+//
+//	The first and last functions within the CEG SDK that must be called are : 
+//		Steamworks_InitCEGLibrary()
+//		Steamworks_TermCEGLibrary()
+//
+//	There are alternate versions of these functions, for people who restrict their usage of the 
+//	CEG SDK to a subset of the available API's  (more on the subset later).  These functions are : 
+//
+//		Steamworks_MinimumInitCEGLibrary()
+//		Steamworks_MinimumTermCEGLibrary().
+//
+//	In the event that the CEG library is initialized through Steamworks_InitCEGLibrary(), then the 
+//	following functions must also be called, on each thread on which CEG code may execute, before any
+//	other CEG code code executes on the thread (these functions are not necessary if Steamworks_MinimumInitCEGLibrary() is called).
+//
+//		Steamworks_RegisterThread()
+//		Steamworks_UnRegisterThread().
+//
+//	The only function which can be called before Steamworks_RegisterThread() is Steamworks_InitCEGLibrary().
+//	Steamworks_RegisterThread() must be called on the thread that calls Steamworks_InitCEGLibrary(), if it calls any 
+//	other CEG functions.
+//	For example, your main() will probably look like : 
+//
+//	int main( int argc, char* argv[] ) 
+//	{
+//		Steamworks_InitCEGLibrary();
+//		Steamworks_RegisterThread();
+//
+//		/* Real work here */
+//
+//		Steamworks_UnRegisterThread();
+//		Steamworks_TermCEGLibrary();
+//		return	0;
+//	}
+//
+//
+//
+//	CEG Minimum API : 
+//
+//		Steamworks_SimpleCheck()
+//
+//	This API is provided for people who are trying to combine CEG with other DRM technology.
+//	This function does a very basic check that the machine is executing on the machine it was produced for.
+//	This function doesn't conceal any of the data it is using to evaluate the machine, and therefore should not be 
+//	used with the full CEG SDK.   It it not necessary to call Steamworks_RegisterThread()/Steamworks_UnRegisterThread()
+//	if CEG API usage is restricted to this function.
+//
+//	CEG Full API's : 
+//
+//	The full set of CEG API's takes the form of direct function calls, who's performance impacts may be easily analyzed
+//	versus macros, which cause sophisticated manipulations of your .obj files before the final executable is linked.
+//
+//
+//	Direct Functions Calls -
+//		Steamworks_TestSecret()		
+//		Steamworks_TestSecretAlways(), 
+//		Steamorks_SelfCheck().
+//
+//	Steamworks_TestSecret() and Steamworks_TestSecretAlways() are focused on evaluating the current 
+//	computer to determine whether it is the machine the binary was produced for.
+//	Because a hacker may be 'tracing' all windows API calls with a tool such as sysinternal's Process Monitor 
+//	( http://technet.microsoft.com/en-us/sysinternals/bb896645 ), Steamworks_TestSecret() will not always 
+//	evaluate it's secret.   The intention is to make it harder to record CEG activity.
+//	Steamworks_TestSecretAlways() will always evaluate it's portion of secret data.
+//
+//	Steamworks_SelfCheck() - this function is focused on determining whether the executable has been modified.
+//
+//
+//	Macro Mechanisms:
+//
+//	CEG's macro mechanisms attempt to entwine machine specific information into the correct operation of the game 
+//	product.  As a result, unlike CEG function calls (which a hacker can simply stub out), a hacker must 
+//	take the time to determine how the CEG code is entwined within the product, and make a more significant effort
+//	to modify the game.
+//
+//	Specific Macro Mechanisms: 
+//
+//	CEG_EncryptFunction()
+//
+//	The function which contains this macro will be modified, so that the opcodes comprising the function 
+//	are encrypted within the executable file.  The decryption key is derived from machine specific data.
+//	If decryption of the code fails, the function will not be executed, and the game will to continue to run.
+//	Whether the executable immediately terminates or not depends on what the encrypted function does for the game, 
+//	as well as calling convention and architecture issues, as the CEG code may not clean up the stack correctly 
+//	when the function fails to execute.
+//	(Please note : Many CEG functions are themselves encrypted using this mechanism).
+//
+//	This mechanism can be used an unlimited number of times - the following macros have restrictions on 
+//	the number of times they can be used within your executable.
+//
+//	Performance Note :
+//	Every time a function containing CEG_EncryptFunction() macro is invoked, CEG code must execute to 
+//	produce the function in a ready to run form in temporarily allocated memory.
+//	CEG will keep a cached version of the function for up to 10 seconds, so that the full cost of decryption 
+//	is not paid on every invocation.  However, every invocation does incur some CEG overhead to 
+//	either decrypt or locate the cached form and to properly martial the call to the decrypted form of the function.
+//
+//-----------------------------------------
+//	CEG_ProtectFunction()
+//
+//	The function which contains this macro will be modified, so that it's address must be computed
+//	by every caller of the function.   The address computation will involve machine specific data, 
+//	as well as checksum computations which verify that the executable has not been modified.
+//	
+//	This mechanism cannot be used (in conjunction with CEG_Define_Constant_Function) more then 130 times.
+//	
+//	Performance Note:
+//
+//	The full cost of the CEG_ProtectFunction() will be paid on every call of the target function.
+//	Because this mechanism involves computing checksums of the executable image, this will be more 
+//	expensive then CEG_EncryptFunction().  However, this mechanism is much more likely to cause problems
+//	for somebody who is attacking the executable with a debugger, as the checksums are likely to find
+//	the breakpoints being used by the debugger. 
+//
+//----------------------------------------
+//	CEG_Define_Constant_Function( name, value )
+//	CEG_Declare_Constant_Function( name )
+//	CEG_GetConstantValue( name )
+//
+//	These macros create and declare a functions that the game can use to get interesting constants 
+//	for game play.  (i.e. Field Of View angle, maximum player velocity etc...)
+//
+//	Computation of CEG_GetConstantValue() involves machine specific information as well as checksums
+//	of the executing binary (same as CEG_ProtectFunction).
+//	If the machine is different, or the executable has been modified, then the results returned 
+//	by CEG_GetConstantValue() will be different.   The results in the game will depend on how
+//	the constant is used.
+//
+//	The same Performance Note as for CEG_ProtectFunction() apply to this mechanism.
+//
+//	
+//	Some General Notes on CEG's macro mechanisms:
+//
+//	The Compiler can eliminate CEG_ProtectFunction() and CEG_EncryptFunction() if it chooses to 
+//	inline your function !!!  In general, it's better to use these macros only in function which appear in 
+//	.cpp files (not in inline functions which appear in header files).   It's also better if the function 
+//	in which CEG_ProtectFunction() or CEG_EncryptFunction() is placed is not called from within the same file!
+//
+//	C++ Constructors and Destructors : 
+//
+//	You can use CEG_ProtectFunction() and CEG_EncryptFunction() within your C++ constructors.
+//	HOWEVER - if there is a global variable that invokes the constructor, you will be invoking 
+//	the CEG mechanisms before you have executed Steamworks_InitCEGLibrary() - and this will probably crash your game.
+//

+//	Many of the CEG functions implement below compute CRC's over the executing image 
+//	of the game when invoked.  This results in their performance impact varying with
+//	the size of the game executable file.
+//	A typical result for Steamworks_SelfCheck() and CEG_Protect_Member_Function() is 
+//	3ms of overhead in a 6MB executable.  (Measured in L4D2).
+//
+//	In order to allow more fine grain control of which part of the executable is covered

+//	Executable code that is placed in this section WILL NOT have any CRC's covering the code.
+//	To place code in this section on an entire source file basis use '#pragma code_seg( NO_CEG_SECTION )'

+//	Care should be taken that the marked code cannot be modified to prevent execution of CEG checks.
+//	Do not put direct CEG call sites into this section, or most of the call stack leading to a CEG call site.
+//	This can be used to improve the performance of the Steamwork_SelfCheck() and CEG_Protect_Member_Function() mechanisms
+//	as they will operate on a smaller portion of the game image.

+////////////////////////////////////////////////////////////////////////////////
+
+	
+//
+//	The flowing three macros :
+//		CEG_Define_Constant_Function( name, value ), 
+//		CEG_Declare_Constant_Function( name ), 
+//		CEG_GetConstantValue( name ) 
+//
+//	Operate together to provide another CEG mechanism for protecting your binary.
+//
+//	Example usage : 
+//	
+//	header.h : 
+//  /* macro is at File Scope !*/
+//	CEG_Declare_Constant_Function( ZombiesPerSecond ) ; 
+//
+//	main.cpp : 
+//	/* macro is at File Scope !*/
+//	CEG_Define_Constant_Function( ZombiesPerSecond, 17 ) ; 
+//
+//	zombies.cpp : 
+//	/* CEG_GetConstantValue( ZombiesPerSecond ) must be used within a  function !*/
+//
+//	void
+//	ClockTick() 
+//	{
+//		if( ElapsedTime > 1 ) /* Has 1 second passed ? */
+//		{
+//			DWORD	cZombies = CEG_GetConstantValue( ZombiesPerSecond ) ; 
+//			for( DWORD i=0; i<cZombies; ++i ) 
+//			{
+//				/* Create a Zombie !*/
+//			}
+//		}
+//	}
+//
+//	Explanation : 
+//
+//	CEG_Define_Constant_Fucntion( ZombiesPerSecond, 17 ) defines a function 
+//	that will return 17 (as a DWORD) every time it is called, IF your executable
+//	has not been tampered with, or copied.   This function must NOT be inlined, 
+//	when your game is CEG'd, the code bytes of the function will be modified.
+//	Putting the Definition in the same file as the usage may allow aggressive compiler 
+//	settings to inline some usages of the function - we recommend that the definition 
+//	never appear with the usage.
+//
+//	CEG_Declare_Constant_Function( ZombiesPerSecond ) generates an extern declaration
+//	of this function.
+//
+//	CEG_GetConstantValue( ZombiesPerSecond ) calls the function defined by 
+//	CEG_Define_Constant_Function() and declared by CEG_Declare_Constant_Function().
+//
+//	How it Works : 
+//	
+//	This mechanism is very similar to that provided by CEG_Protect_Member_Function()
+//	The CEG code will compute checksums over your executing image, and these checksums 
+//	will come to the result specified in the CEG_Declare_Constant_Function() if the 
+//	image has not been tampered with.   If a hacker has tampered, this will return a 
+//	random number.    By choosing appropriate constants, your game may be rendered 
+//	unplayable, although CEG will not crash the game.
+//
+//	Recommendation : 
+//
+//	This CEG functionality degrades the game when the game is tampered with.
+//	It should be used in conjunction with all the other CEG mechanisms.
+//	The other CEG mechanisms will immediately crash the game when tampered, 
+//	which makes these mechanisms easy to identify in support calls, online forums etc...
+//
+//	Make sure you include a small number of Steamworks_TestSecretAlways() call 
+//	during the start/load of the game.  These will catch Casual Piracy.
+//	The game degradation caused through this the CEG_Define_Constant_Function() is 
+//	directed at sophisticated pirates, who will have a hard time tracking 
+//	down the results of their modifications of the game image.
+//
+//	IMPORTANT NOTE ABOUT THE VALUE ZERO !
+//
+//	Don't use :
+//	CEG_Define_Constant_Function( Zero, 0 ) 
+//	or : 
+//	CEG_Define_ConstantFloat_Function( FloatZero, 0.0f ) 
+//
+//	The .obj and .exe parsing mechanisms assume 0 (also known as NULL) is an unbound 
+//	usage - and the resulting calls to CEG_GetConstantValue() will not return 0 (zero)
+//	(The string 'zero' is fine, of course).

+/***************************************************
+****************************************************
+
+	CEG_ProtectFunction and CEG_EncryptFunction
+	
+	These macros must be placed within the body of a function.
+	Here is a small example, which describes how CEG_ProtectFunction() operates :
+
+
+	class CMyClass {
+					virtual   void MyVirtualFunction( int SomeArg ) ; 
+	} ; 
+
+	__declspec(noinline)	// This is necessary to prevent compiler optimizations from eliminating CEG check.
+	void
+	CMyClass::MyVirtualFunction( int SomeArg ) {
+		CEG_ProtectFunction();
+
+		//
+		//            Now do the real work !
+		//
+	}
+
+	Void ExampleCall(CMyClass * p )
+	{
+					p->MyVirtualFunction( EXAMPLE_CONSTANT ) ; }
+	}
+
+
+	Now what happens to your binary is the following : 
+
+	The vtable for CMyClass has been changed to reference a CEG function.  When ExampleCall() is executed, 
+	It will actually end up calling CEG code through the vtable.   This CEG code preserves the state of the stack 
+	and arguments in a fashion similar to the CRT setjmp() function.
+	
+	The CEG code will then compute a checksum that incorporates machine identifying information into the checksum.
+
+	If nobody has modified the executable (by setting breakpoints, or by changing the executable file) and the executable
+	is running on the machine it was produced for, then the checksum results in the address of CMyClass::MyVirtualFunction().
+
+	In this case, CEG will patch the CONTEXT it got from it's setjmp() operation and longjmp() to CMyClass::MyVirtualFunction().
+	The setjmp()/longjmp() manipulations allow CEG to do it's work, without having to understand the calling convention 
+	between ExampleCall() and CMyClass::MyVirtualFunction().
+
+	Before the CEG code invokes longjmp(), it checks that the address it computed is correct, by computing an MD5 of the 
+	address, and comparing this to a stored MD5.  If this comparison fail, CEG terminates the process directly.
+
+	You can use CEG_ProtectFunction()/CEG_EncryptFunction() in any kind of function - 
+		C++ member functions, C++ static member functions etc....
