 // @abstract
 // An abstract thread quality of service (QOS) classification.
 //
 // @discussion
 // Thread quality of service (QOS) classes are ordered abstract representations
 // of the nature of work that is expected to be performed by a pthread, dispatch
 // queue, or NSOperation. Each class specifies a maximum thread scheduling
 // priority for that band (which may be used in combination with a relative
 // priority offset within the band), as well as quality of service
 // characteristics for timer latency, CPU throughput, I/O throughput, network
 // socket traffic management behavior and more.
 //
 // A best effort is made to allocate available system resources to every QOS
 // class. Quality of service degredation only occurs during system resource
 // contention, proportionally to the QOS class. That said, QOS classes
 // representing user-initiated work attempt to achieve peak throughput while
 // QOS classes for other work attempt to achieve peak energy and thermal
 // efficiency, even in the absence of contention. Finally, the use of QOS
 // classes does not allow threads to supersede any limits that may be applied
 // to the overall process.
 
 // !
 // @constant QOS_CLASS_USER_INTERACTIVE
 // @abstract A QOS class which indicates work performed by this thread
 // is interactive with the user.
 // @discussion Such work is requested to run at high priority relative to other
 // work on the system. Specifying this QOS class is a request to run with
 // nearly all available system CPU and I/O bandwidth even under contention.
 // This is not an energy-efficient QOS class to use for large tasks. The use of
 // this QOS class should be limited to critical interaction with the user such
 // as handling events on the main event loop, view drawing, animation, etc.
 //
 // @constant QOS_CLASS_USER_INITIATED
 // @abstract A QOS class which indicates work performed by this thread
 // was initiated by the user and that the user is likely waiting for the
 // results.
 // @discussion Such work is requested to run at a priority below critical user-
 // interactive work, but relatively higher than other work on the system. This
 // is not an energy-efficient QOS class to use for large tasks. Its use
 // should be limited to operations of short enough duration that the user is
 // unlikely to switch tasks while waiting for the results. Typical
 // user-initiated work will have progress indicated by the display of
 // placeholder content or modal user interface.
 //
 // @constant QOS_CLASS_DEFAULT
 // @abstract A default QOS class used by the system in cases where more specific
 // QOS class information is not available.
 // @discussion Such work is requested to run at a priority below critical user-
 // interactive and user-initiated work, but relatively higher than utility and
 // background tasks. Threads created by pthread_create() without an attribute
 // specifying a QOS class will default to QOS_CLASS_DEFAULT. This QOS class
 // value is not intended to be used as a work classification, it should only be
 // set when propagating or restoring QOS class values provided by the system.
 //
 // @constant QOS_CLASS_UTILITY
 // @abstract A QOS class which indicates work performed by this thread
 // may or may not be initiated by the user and that the user is unlikely to be
 // immediately waiting for the results.
 // @discussion Such work is requested to run at a priority below critical user-
 // interactive and user-initiated work, but relatively higher than low-level
 // system maintenance tasks. The use of this QOS class indicates the work
 // should be run in an energy and thermally-efficient manner. The progress of
 // utility work may or may not be indicated to the user, but the effect of such
 // work is user-visible.
 //
 // @constant QOS_CLASS_BACKGROUND
 // @abstract A QOS class which indicates work performed by this thread was not
 // initiated by the user and that the user may be unaware of the results.
 // @discussion Such work is requested to run at a priority below other work.
 // The use of this QOS class indicates the work should be run in the most energy
 // and thermally-efficient manner.
 //
 // @constant QOS_CLASS_UNSPECIFIED
 // @abstract A QOS class value which indicates the absence or removal of QOS
 // class information.
 // @discussion As an API return value, may indicate that threads or pthread
 // attributes were configured with legacy API incompatible or in conflict with
 // the QOS class system.

 // This SDK is designed to work with clang and specific versions of
 // gcc >= 4.0 with Apple's patch sets
 
 // Compatibility with compilers and environments that don't support compiler
 // feature checking function-like macros.
 
 // The __CONCAT macro is used to concatenate parts of symbol names, e.g.
 // with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
 // The __CONCAT macro is a bit tricky -- make sure you don't put spaces
 // in between its arguments.  __CONCAT can also concatenate double-quoted
 // strings produced by the __STRING macro, but this only works with ANSI C.
 
 // In non-ANSI C environments, new programs will want ANSI-only C keywords
 // deleted from the program and old programs will want them left alone.
 // When using a compiler other than gcc, programs using the ANSI C keywords
 // const, inline etc. as normal identifiers should define -DNO_ANSI_KEYWORDS.
 // When using "gcc -traditional", we assume that this is the intent; if
 // __GNUC__ is defined but __STDC__ is not, we leave the new keywords alone.
 
 // __unused denotes variables and functions that may not be used, preventing
 // the compiler from warning about it if not used.
 
 // __used forces variables and functions to be included even if it appears
 // to the compiler that they are not used (and would thust be discarded).
 
 // __cold marks code used for debugging or that is rarely taken
 // and tells the compiler to optimize for size and outline code.
 
 // __deprecated causes the compiler to produce a warning when encountering
 // code using the deprecated functionality.
 // __deprecated_msg() does the same, and compilers that support it will print
 // a message along with the deprecation warning.
 // This may require turning on such warning with the -Wdeprecated flag.
 // __deprecated_enum_msg() should be used on enums, and compilers that support
 // it will print the deprecation warning.
 // __kpi_deprecated() specifically indicates deprecation of kernel programming
 // interfaces in Kernel.framework used by KEXTs.
 
 // __unavailable causes the compiler to error out when encountering
 // code using the tagged function of variable.
 
 // Delete pseudo-keywords wherever they are not available or needed.
 
 // We use `__restrict' as a way to define the `restrict' type qualifier
 // without disturbing older software that is unaware of C99 keywords.
 
 // Compatibility with compilers and environments that don't support the
 // nullability feature.
 
 // __disable_tail_calls causes the compiler to not perform tail call
 // optimization inside the marked function.
 
 // __not_tail_called causes the compiler to prevent tail call optimization
 // on statically bound calls to the function.  It has no effect on indirect
 // calls.  Virtual functions, objective-c methods, and functions marked as
 // "always_inline" cannot be marked as __not_tail_called.
 
 // __result_use_check warns callers of a function that not using the function
 // return value is a bug, i.e. dismissing malloc() return value results in a
 // memory leak.
 
 // __swift_unavailable causes the compiler to mark a symbol as specifically
 // unavailable in Swift, regardless of any other availability in C.
 
 // __abortlike is the attribute to put on functions like abort() that are
 // typically used to mark assertions. These optimize the codegen
 // for outlining while still maintaining debugability.
 
 // Declaring inline functions within headers is error-prone due to differences
 // across various versions of the C language and extensions.  __header_inline
 // can be used to declare inline functions within system headers.  In cases
 // where you want to force inlining instead of letting the compiler make
 // the decision, you can use __header_always_inline.
 //
 // Be aware that using inline for functions which compilers may also provide
 // builtins can behave differently under various compilers.  If you intend to
 // provide an inline version of such a function, you may want to use a macro
 // instead.
 //
 // The check for !__GNUC__ || __clang__ is because gcc doesn't correctly
 // support c99 inline in some cases:
 // http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55965
 
 // Compiler-dependent macros that bracket portions of code where the
 // "-Wunreachable-code" warning should be ignored. Please use sparingly.
 
 // Compiler-dependent macros to declare that functions take printf-like
 // or scanf-like arguments.  They are null except for versions of gcc
 // that are known to support the features properly.  Functions declared
 // with these attributes will cause compilation warnings if there is a
 // mismatch between the format string and subsequent function parameter
 // types.
 
 // Source compatibility only, ID string not emitted in object file
 
 // __alloc_size can be used to label function arguments that represent the
 // size of memory that the function allocates and returns. The one-argument
 // form labels a single argument that gives the allocation size (where the
 // arguments are numbered from 1):
 //
 // void	*malloc(size_t __size) __alloc_size(1);
 //
 // The two-argument form handles the case where the size is calculated as the
 // product of two arguments:
 //
 // void	*calloc(size_t __count, size_t __size) __alloc_size(1,2);
 
 // COMPILATION ENVIRONMENTS -- see compat(5) for additional detail
 //
 // DEFAULT	By default newly complied code will get POSIX APIs plus
 //		Apple API extensions in scope.
 //
 //		Most users will use this compilation environment to avoid
 //		behavioral differences between 32 and 64 bit code.
 //
 // LEGACY	Defining _NONSTD_SOURCE will get pre-POSIX APIs plus Apple
 //		API extensions in scope.
 //
 //		This is generally equivalent to the Tiger release compilation
 //		environment, except that it cannot be applied to 64 bit code;
 //		its use is discouraged.
 //
 //		We expect this environment to be deprecated in the future.
 //
 // STRICT	Defining _POSIX_C_SOURCE or _XOPEN_SOURCE restricts the
 //		available APIs to exactly the set of APIs defined by the
 //		corresponding standard, based on the value defined.
 //
 //		A correct, portable definition for _POSIX_C_SOURCE is 200112L.
 //		A correct, portable definition for _XOPEN_SOURCE is 600L.
 //
 //		Apple API extensions are not visible in this environment,
 //		which can cause Apple specific code to fail to compile,
 //		or behave incorrectly if prototypes are not in scope or
 //		warnings about missing prototypes are not enabled or ignored.
 //
 // In any compilation environment, for correct symbol resolution to occur,
 // function prototypes must be in scope.  It is recommended that all Apple
 // tools users add either the "-Wall" or "-Wimplicit-function-declaration"
 // compiler flags to their projects to be warned when a function is being
 // used without a prototype in scope.
 
 // These settings are particular to each product.
 // Platform: MacOSX
 // #undef __DARWIN_ONLY_UNIX_CONFORMANCE (automatically set for 64-bit)
 
 // The __DARWIN_ALIAS macros are used to do symbol renaming; they allow
 // legacy code to use the old symbol, thus maintaining binary compatibility
 // while new code can use a standards compliant version of the same function.
 //
 // __DARWIN_ALIAS is used by itself if the function signature has not
 // changed, it is used along with a #ifdef check for __DARWIN_UNIX03
 // if the signature has changed.  Because the __LP64__ environment
 // only supports UNIX03 semantics it causes __DARWIN_UNIX03 to be
 // defined, but causes __DARWIN_ALIAS to do no symbol mangling.
 //
 // As a special case, when XCode is used to target a specific version of the
 // OS, the manifest constant __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
 // will be defined by the compiler, with the digits representing major version
 // time 100 + minor version times 10 (e.g. 10.5 := 1050).  If we are targeting
 // pre-10.5, and it is the default compilation environment, revert the
 // compilation environment to pre-__DARWIN_UNIX03.

 // POSIX.1 requires that the macros we test be defined before any standard
 // header file is included.  This permits us to convert values for feature
 // testing, as necessary, using only _POSIX_C_SOURCE.
 //
 // Here's a quick run-down of the versions:
 //  defined(_POSIX_SOURCE)		1003.1-1988
 //  _POSIX_C_SOURCE == 1L		1003.1-1990
 //  _POSIX_C_SOURCE == 2L		1003.2-1992 C Language Binding Option
 //  _POSIX_C_SOURCE == 199309L		1003.1b-1993
 //  _POSIX_C_SOURCE == 199506L		1003.1c-1995, 1003.1i-1995,
 //					and the omnibus ISO/IEC 9945-1: 1996
 //  _POSIX_C_SOURCE == 200112L		1003.1-2001
 //  _POSIX_C_SOURCE == 200809L		1003.1-2008
 //
 // In addition, the X/Open Portability Guide, which is now the Single UNIX
 // Specification, defines a feature-test macro which indicates the version of
 // that specification, and which subsumes _POSIX_C_SOURCE.
 
 // Deal with IEEE Std. 1003.1-1990, in which _POSIX_C_SOURCE == 1L.
 
 // Deal with IEEE Std. 1003.2-1992, in which _POSIX_C_SOURCE == 2L.
 
 // Deal with various X/Open Portability Guides and Single UNIX Spec.
 
 // Deal with all versions of POSIX.  The ordering relative to the tests above is
 // important.

 // Set a single macro which will always be defined and can be used to determine
 // the appropriate namespace.  For POSIX, these values will correspond to
 // _POSIX_C_SOURCE value.  Currently there are two additional levels corresponding
 // to ANSI (_ANSI_SOURCE) and Darwin extensions (_DARWIN_C_SOURCE)
 
 // If the developer has neither requested a strict language mode nor a version
 // of POSIX, turn on functionality provided by __STDC_WANT_LIB_EXT1__ as part
 // of __DARWIN_C_FULL.
 
 // long long is not supported in c89 (__STRICT_ANSI__), but g++ -ansi and

 //
 //  Public darwin-specific feature macros
 //
 
 // _DARWIN_FEATURE_64_BIT_INODE indicates that the ino_t type is 64-bit, and
 // structures modified for 64-bit inodes (like struct stat) will be used.
 
 // _DARWIN_FEATURE_64_ONLY_BIT_INODE indicates that the ino_t type may only
 // be 64-bit; there is no support for 32-bit ino_t when this macro is defined
 // (and non-zero).  There is no struct stat64 either, as the regular
 // struct stat will already be the 64-bit version.
 
 // _DARWIN_FEATURE_ONLY_VERS_1050 indicates that only those APIs updated
 // in 10.5 exists; no pre-10.5 variants are available.
 
 // _DARWIN_FEATURE_ONLY_UNIX_CONFORMANCE indicates only UNIX conforming API
 // are available (the legacy BSD APIs are not available)
 
 // _DARWIN_FEATURE_UNIX_CONFORMANCE indicates whether UNIX conformance is on,
 // and specifies the conformance level (3 is SUSv3)
 
 // This macro casts away the qualifier from the variable
 //
 // Note: use at your own risk, removing qualifiers can result in
 // catastrophic run-time failures.
 
 // __XNU_PRIVATE_EXTERN is a linkage decoration indicating that a symbol can be
 // used from other compilation units, but not other libraries or executables.
 
 // Architecture validation for current SDK
 
 // Similar to OS_ENUM/OS_CLOSED_ENUM/OS_OPTIONS/OS_CLOSED_OPTIONS
 //
 // This provides more advanced type checking on compilers supporting
 // the proper extensions, even in C.

 // The rune type below is declared to be an ``int'' instead of the more natural
 // ``unsigned long'' or ``long''.  Two things are happening here.  It is not
 // unsigned so that EOF (-1) can be naturally assigned to it and used.  Also,
 // it looks like 10646 will be a 31 bit standard.  This means that if your
 // ints cannot hold 32 bits, you will be in trouble.  The reason an int was
 // chosen over a long is that the is*() and to*() routines take ints (says
 // ANSI C), but they use __darwin_ct_rune_t instead of int.  By changing it
 // here, you lose a bit of ANSI conformance, but your programs will still
 // work.
 //
 // NOTE: rune_t is not covered by ANSI nor other standards, and should not
 // be instantiated outside of lib/libc/locale.  Use wchar_t.  wchar_t and

 //
 //     These macros are for use in OS header files. They enable function prototypes
 //     and Objective-C methods to be tagged with the OS version in which they
 //     were first available; and, if applicable, the OS version in which they
 //     became deprecated.
 //
 //     The desktop Mac OS X and iOS each have different version numbers.
 //     The __OSX_AVAILABLE_STARTING() macro allows you to specify both the desktop
 //     and iOS version numbers.  For instance:
 //         __OSX_AVAILABLE_STARTING(__MAC_10_2,__IPHONE_2_0)
 //     means the function/method was first available on Mac OS X 10.2 on the desktop
 //     and first available in iOS 2.0 on the iPhone.
 //
 //     If a function is available on one platform, but not the other a _NA (not
 //     applicable) parameter is used.  For instance:
 //             __OSX_AVAILABLE_STARTING(__MAC_10_3,__IPHONE_NA)
 //     means that the function/method was first available on Mac OS X 10.3, and it
 //     currently not implemented on the iPhone.
 //
 //     At some point, a function/method may be deprecated.  That means Apple
 //     recommends applications stop using the function, either because there is a
 //     better replacement or the functionality is being phased out.  Deprecated
 //     functions/methods can be tagged with a __OSX_AVAILABLE_BUT_DEPRECATED()
 //     macro which specifies the OS version where the function became available
 //     as well as the OS version in which it became deprecated.  For instance:
 //         __OSX_AVAILABLE_BUT_DEPRECATED(__MAC_10_0,__MAC_10_5,__IPHONE_NA,__IPHONE_NA)
 //     means that the function/method was introduced in Mac OS X 10.0, then
 //     became deprecated beginning in Mac OS X 10.5.  On iOS the function
 //     has never been available.
 //
 //     For these macros to function properly, a program must specify the OS version range
 //     it is targeting.  The min OS version is specified as an option to the compiler:
 //     -mmacosx-version-min=10.x when building for Mac OS X, and -miphoneos-version-min=y.z
 //     when building for the iPhone.  The upper bound for the OS version is rarely needed,
 //     but it can be set on the command line via: -D__MAC_OS_X_VERSION_MAX_ALLOWED=10x0 for
 //     Mac OS X and __IPHONE_OS_VERSION_MAX_ALLOWED = y0z00 for iOS.
 //
 //     Examples:
 //
 //         A function available in Mac OS X 10.5 and later, but not on the phone:
 //
 //             extern void mymacfunc() __OSX_AVAILABLE_STARTING(__MAC_10_5,__IPHONE_NA);
 //
 //
 //         An Objective-C method in Mac OS X 10.5 and later, but not on the phone:
 //
 //             @interface MyClass : NSObject
 //             -(void) mymacmethod __OSX_AVAILABLE_STARTING(__MAC_10_5,__IPHONE_NA);
 //             @end
 //
 //
 //         An enum available on the phone, but not available on Mac OS X:
 //
 //             #if __IPHONE_OS_VERSION_MIN_REQUIRED
 //                 enum { myEnum = 1 };
 //             #endif
 //            Note: this works when targeting the Mac OS X platform because
 //            __IPHONE_OS_VERSION_MIN_REQUIRED is undefined which evaluates to zero.
 //
 //
 //         An enum with values added in different iPhoneOS versions:
 //
 // 			enum {
 // 			    myX  = 1,	// Usable on iPhoneOS 2.1 and later
 // 			    myY  = 2,	// Usable on iPhoneOS 3.0 and later
 // 			    myZ  = 3,	// Usable on iPhoneOS 3.0 and later
 // 				...
 // 		      Note: you do not want to use #if with enumeration values
 // 			  when a client needs to see all values at compile time
 // 			  and use runtime logic to only use the viable values.
 //
 //
 //     It is also possible to use the *_VERSION_MIN_REQUIRED in source code to make one
 //     source base that can be compiled to target a range of OS versions.  It is best
 //     to not use the _MAC_* and __IPHONE_* macros for comparisons, but rather their values.
 //     That is because you might get compiled on an old OS that does not define a later
 //     OS version macro, and in the C preprocessor undefined values evaluate to zero
 //     in expresssions, which could cause the #if expression to evaluate in an unexpected
 //     way.
 //
 //         #ifdef __MAC_OS_X_VERSION_MIN_REQUIRED
 //             // code only compiled when targeting Mac OS X and not iPhone
 //             // note use of 1050 instead of __MAC_10_5
 //             #if __MAC_OS_X_VERSION_MIN_REQUIRED < 1050
 //                 // code in here might run on pre-Leopard OS
 //             #else
 //                 // code here can assume Leopard or later
 //             #endif
 //         #endif
 //
 //
 
 // __API_TO_BE_DEPRECATED is used as a version number in API that will be deprecated
 // in an upcoming release. This soft deprecation is an intermediate step before formal
 // deprecation to notify developers about the API before compiler warnings are generated.
 // You can find all places in your code that use soft deprecated API by redefining the
 // value of this macro to your current minimum deployment target, for example:
 // (macOS)
 //   clang -D__API_TO_BE_DEPRECATED=10.12 <other compiler flags>
 // (iOS)
 //   clang -D__API_TO_BE_DEPRECATED=11.0 <other compiler flags>
 
 // __MAC_NA is not defined to a value but is uses as a token by macros to indicate that the API is unavailable
 
 // __IPHONE_NA is not defined to a value but is uses as a token by macros to indicate that the API is unavailable

 //	mach_port_t - a named port right
 //
 //	In user-space, "rights" are represented by the name of the
 //	right in the Mach port namespace.  Even so, this type is
 //	presented as a unique one to more clearly denote the presence
 //	of a right coming along with the name.
 //
 //	Often, various rights for a port held in a single name space
 //	will coalesce and are, therefore, be identified by a single name
 //	[this is the case for send and receive rights].  But not
 //	always [send-once rights currently get a unique name for
 //	each right].
 //
 //	This definition of mach_port_t is only for user-space.
