 26 /*     
 27    These macros are for use in OS header files. They enable function prototypes
 28    and Objective-C methods to be tagged with the OS version in which they
 29    were first available; and, if applicable, the OS versions in which they
 30    became deprecated and obsoleted.
 31     
 32    The desktop Mac OS X and iOS each have different version numbers.
 33    The __OSX_AVAILABLE_STARTING() macro allows you to specify both the desktop
 34    and iOS version numbers.  For instance:
 35        __OSX_AVAILABLE_STARTING(__MAC_10_2,__IPHONE_2_0)
 36    means the function/method was first available on Mac OS X 10.2 on the desktop
 37    and first available in iOS 2.0 on the iPhone.
 38    
 39    If a function is available on one platform, but not the other a _NA (not
 40    applicable) parameter is used.  For instance:
 41            __OSX_AVAILABLE_STARTING(__MAC_10_3,__IPHONE_NA)
 42    means that the function/method was first available on Mac OS X 10.3, and it
 43    currently not implemented on the iPhone.
 44
 45    At some point, a function/method may be deprecated.  That means Apple
 46    recommends applications stop using the function, either because there is a 
 47    better replacement or the functionality is being phased out.  Deprecated
 48    functions/methods can be tagged with a __OSX_AVAILABLE_BUT_DEPRECATED()
 49    macro which specifies the OS version where the function became available
 50    as well as the OS version in which it became deprecated.  For instance:
 51        __OSX_AVAILABLE_BUT_DEPRECATED(__MAC_10_0,__MAC_10_5,__IPHONE_NA,__IPHONE_NA)
 52    means that the function/method was introduced in Mac OS X 10.0, then
 53    became deprecated beginning in Mac OS X 10.5.  On iOS the function 
 54    has never been available.  
 55    
 56    For these macros to function properly, a program must specify the OS version range 
 57    it is targeting.  The min OS version is specified as an option to the compiler:
 58    -mmacosx-version-min=10.x when building for Mac OS X, and -miphoneos-version-min=y.z
 59    when building for the iPhone.  The upper bound for the OS version is rarely needed,
 60    but it can be set on the command line via: -D__MAC_OS_X_VERSION_MAX_ALLOWED=10x0 for
 61    Mac OS X and __IPHONE_OS_VERSION_MAX_ALLOWED = y0z00 for iOS.  
 62    
 63    Examples:
 64
 65        A function available in Mac OS X 10.5 and later, but not on the phone:
 66        
 67            extern void mymacfunc() __OSX_AVAILABLE_STARTING(__MAC_10_5,__IPHONE_NA);
 68
 69
 70        An Objective-C method in Mac OS X 10.5 and later, but not on the phone:
 71        
 72            @interface MyClass : NSObject
 73            -(void) mymacmethod __OSX_AVAILABLE_STARTING(__MAC_10_5,__IPHONE_NA);
 74            @end
 75
 76        
 77        An enum available on the phone, but not available on Mac OS X:
 78        
 79            #if __IPHONE_OS_VERSION_MIN_REQUIRED
 80                enum { myEnum = 1 };
 81            #endif
 82           Note: this works when targeting the Mac OS X platform because 
 83           __IPHONE_OS_VERSION_MIN_REQUIRED is undefined which evaluates to zero. 
 84        
 85
 86        An enum with values added in different iPhoneOS versions:
 87		
 88			enum {
 89			    myX  = 1,	// Usable on iPhoneOS 2.1 and later
 90			    myY  = 2,	// Usable on iPhoneOS 3.0 and later
 91			    myZ  = 3,	// Usable on iPhoneOS 3.0 and later
 92				...
 93		      Note: you do not want to use #if with enumeration values
 94			  when a client needs to see all values at compile time
 95			  and use runtime logic to only use the viable values.
 96			  
 97
 98    It is also possible to use the *_VERSION_MIN_REQUIRED in source code to make one
 99    source base that can be compiled to target a range of OS versions.  It is best
100    to not use the _MAC_* and __IPHONE_* macros for comparisons, but rather their values.
101    That is because you might get compiled on an old OS that does not define a later
102    OS version macro, and in the C preprocessor undefined values evaluate to zero
103    in expresssions, which could cause the #if expression to evaluate in an unexpected
104    way.
105    
106        #ifdef __MAC_OS_X_VERSION_MIN_REQUIRED
107            // code only compiled when targeting Mac OS X and not iPhone
108            // note use of 1050 instead of __MAC_10_5
109            #if __MAC_OS_X_VERSION_MIN_REQUIRED < 1050
110                // code in here might run on pre-Leopard OS
111            #else
112                // code here can assume Leopard or later
113            #endif
114        #endif
