#ifndef __AVAILABILITY__
#define __AVAILABILITY__
/*
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>

* TARGET_CPU_MIPS - Compiler is generating MIPS instructions
* TARGET_CPU_SPARC - Compiler is generating Sparc instructions
* TARGET_CPU_ALPHA - Compiler is generating Dec Alpha instructions
*
*
* TARGET_OS_*
* These conditionals specify in which Operating System the generated code will
* run. Indention is used to show which conditionals are evolutionary subclasses.
*
* The MAC/WIN32/UNIX conditionals are mutually exclusive.
* The IOS/TV/WATCH conditionals are mutually exclusive.
*
*
* TARGET_OS_WIN32 - Generated code will run under 32-bit Windows
* TARGET_OS_UNIX - Generated code will run under some Unix (not OSX)
* TARGET_OS_MAC - Generated code will run under Mac OS X variant
* TARGET_OS_OSX - Generated code will run under OS X devices
* TARGET_OS_IPHONE - Generated code for firmware, devices, or simulator
* TARGET_OS_IOS - Generated code will run under iOS
* TARGET_OS_TV - Generated code will run under Apple TV OS
* TARGET_OS_WATCH - Generated code will run under Apple Watch OS
* TARGET_OS_BRIDGE - Generated code will run under Bridge devices

*
* TARGET_RT_LITTLE_ENDIAN - Generated code uses little endian format for integers
* TARGET_RT_BIG_ENDIAN - Generated code uses big endian format for integers
* TARGET_RT_64_BIT - Generated code uses 64-bit pointers
* TARGET_RT_MAC_CFM - TARGET_OS_MAC is true and CFM68K or PowerPC CFM (TVectors) are used

NOTE: If your compiler errors out here then support for your compiler
has not yet been added to TargetConditionals.h.
TargetConditionals.h is designed to be plug-and-play. It auto detects
which compiler is being run and configures the TARGET_ conditionals
appropriately.
The short term work around is to set the TARGET_CPU_ and TARGET_OS_
on the command line to the compiler (e.g. -DTARGET_CPU_MIPS=1 -DTARGET_OS_UNIX=1)
The long term solution is to add a new case to this file which
auto detects your compiler and sets up the TARGET_ conditionals.
Then submit the changes to Apple Computer.

* class of the calling thread. If the block object is submitted to a queue,
* this replaces the default behavior of associating the submitted block

* This flag is ignored if a specific QOS class is assigned with

* Flag indicating that execution of a dispatch block object submitted to a

* assigned to the block (resp. associated with the block at the time of
* submission). The latter will only be used if the queue in question does not
* have an assigned QOS class, as long as doing so does not result in a QOS
* class lower than the QOS class inherited from the queue's target queue.
* This flag is the default when a dispatch block object is submitted to a queue

* @abstract
* Create a new dispatch block object on the heap from an existing block and
* the given flags.
*
* @discussion
* The provided block is Block_copy'ed to the heap and retained by the newly
* created dispatch block object.
*
* The returned dispatch block object is intended to be submitted to a dispatch
* queue with dispatch_async() and related functions, but may also be invoked
* directly. Both operations can be performed an arbitrary number of times but
* only the first completed execution of a dispatch block object can be waited
* on with dispatch_block_wait() or observed with dispatch_block_notify().
*
* If the returned dispatch block object is submitted to a dispatch queue, the
* submitted block instance will be associated with the QOS class current at the
* time of submission, unless one of the following flags assigned a specific QOS
* class (or no QOS class) at the time of block creation:
* - DISPATCH_BLOCK_ASSIGN_CURRENT
* - DISPATCH_BLOCK_NO_QOS_CLASS
* - DISPATCH_BLOCK_DETACHED
* The QOS class the block object will be executed with also depends on the QOS
* class assigned to the queue and which of the following flags was specified or
* defaulted to:
* - DISPATCH_BLOCK_INHERIT_QOS_CLASS (default for asynchronous execution)
* - DISPATCH_BLOCK_ENFORCE_QOS_CLASS (default for synchronous execution)
* See description of dispatch_block_flags_t for details.
*
* If the returned dispatch block object is submitted directly to a serial queue
* and is configured to execute with a specific QOS class, the system will make
* a best effort to apply the necessary QOS overrides to ensure that blocks
* submitted earlier to the serial queue are executed at that same QOS class or
* higher.
*
* @param flags
* Configuration flags for the block object.
* Passing a value that is not a bitwise OR of flags from dispatch_block_flags_t
* results in NULL being returned.
*
* @param block
* The block to create the dispatch block object from.
*

* @discussion
* The provided block is Block_copy'ed to the heap and retained by the newly

* on with dispatch_block_wait() or observed with dispatch_block_notify().
*
* If invoked directly, the returned dispatch block object will be executed with
* the assigned QOS class as long as that does not result in a lower QOS class
* than what is current on the calling thread.
*
* If the returned dispatch block object is submitted to a dispatch queue, the
* QOS class it will be executed with depends on the QOS class assigned to the
* block, the QOS class assigned to the queue and which of the following flags
* was specified or defaulted to:
* - DISPATCH_BLOCK_INHERIT_QOS_CLASS: default for asynchronous execution
* - DISPATCH_BLOCK_ENFORCE_QOS_CLASS: default for synchronous execution
* See description of dispatch_block_flags_t for details.
*
* If the returned dispatch block object is submitted directly to a serial queue
* and is configured to execute with a specific QOS class, the system will make
* a best effort to apply the necessary QOS overrides to ensure that blocks
* submitted earlier to the serial queue are executed at that same QOS class or
* higher.
*
* @param flags
* Configuration flags for the new block object.
* Passing a value that is not a bitwise OR of flags from dispatch_block_flags_t
* results in NULL being returned.
*
* @param qos_class

* - QOS_CLASS_USER_INTERACTIVE
* - QOS_CLASS_USER_INITIATED
* - QOS_CLASS_DEFAULT
* - QOS_CLASS_UTILITY
* - QOS_CLASS_BACKGROUND
* - QOS_CLASS_UNSPECIFIED
* Passing QOS_CLASS_UNSPECIFIED is equivalent to specifying the
* DISPATCH_BLOCK_NO_QOS_CLASS flag. Passing any other value results in NULL
* being returned.
*
* @param relative_priority
* A relative priority within the QOS class. This value is a negative
* offset from the maximum supported scheduler priority for the given class.
* Passing a value greater than zero or less than QOS_MIN_RELATIVE_PRIORITY

*
* Dispatch sources are created in an inactive state. After creating the

* a call must be made to dispatch_activate() in order to begin event delivery.
*
* Calling dispatch_set_target_queue() on a source once it has been activated
* is not allowed (see dispatch_activate() and dispatch_set_target_queue()).
*
* For backward compatibility reasons, dispatch_resume() on an inactive,
* and not otherwise suspended source has the same effect as calling
* dispatch_activate(). For new code, using dispatch_activate() is preferred.

* For the initial timer fire at 'start', the upper limit to the allowable
* delay is set to 'leeway' nanoseconds. For the subsequent timer fires at
* 'start' + N * 'interval', the upper limit is MIN('leeway','interval'/2).
*
* The lower limit to the allowable delay may vary with process state such as
* visibility of application UI. If the specified timer source was created with
* a mask of DISPATCH_TIMER_STRICT, the system will make a best effort to

* If 'start' is DISPATCH_TIME_NOW or was created with dispatch_time(3), the
* timer is based on up time (which is obtained from mach_absolute_time() on

/*! @abstract Dequeue an element from a list.
@discussion
Memory barriers are incorporated as needed to permit thread-safe access
to the queue element.
@param __list
The list from which you want to dequeue an element.
@param __offset
The "offset" parameter is the offset (in bytes) of the link field
from the beginning of the data structure being dequeued (<code>__new</code>).
The link field should be a pointer type.
The <code>__offset</code> value needs to be same for all enqueuing and
dequeuing operations on the same list, even if different structure types
are enqueued on that list. The use of <code>offsetset()</code>, defined in
<code>stddef.h</code> is the common way to specify the <code>__offset</code>
value.
IMPORTANT: the memory backing the link field of a queue element must not be
unmapped after OSAtomicDequeue() returns until all concurrent calls to
OSAtomicDequeue() for the same list on other threads have also returned,
as they may still be accessing that memory location.
@result
Returns the most recently enqueued element, or <code>NULL</code> if the
list is empty.

* Definition of a Mach port
*
* Mach ports are the endpoints to Mach-implemented communications
* channels (usually uni-directional message queues, but other types
* also exist).
*
* Unique collections of these endpoints are maintained for each
* Mach task. Each Mach port in the task's collection is given a
* [task-local] name to identify it - and the the various "rights"
* held by the task for that specific endpoint.
*
* This header defines the types used to identify these Mach ports
* and the various rights associated with them. For more info see:
*
* <mach/mach_port.h> - manipulation of port rights in a given space
* <mach/message.h> - message queue [and port right passing] mechanism

math optimizations like those enabled by -ffast-math are turned on.
Thus, (somewhat surprisingly) you only get the fast inline
implementations if such compiler options are NOT enabled. This is
because the inline functions require the compiler to be adhering to
the standard in order to work properly; -ffast-math, among other
things, implies that NaNs don't happen, which allows the compiler to
optimize away checks like x != x, which might lead to things like
isnan(NaN) returning false.

* The value IP_PORTRANGE_HIGH changes the range of candidate port numbers
* into the "high" range. These are reserved for client outbound connections
* which do not want to be filtered by any firewalls.
*
* The value IP_PORTRANGE_LOW changes the range to the "low" are
* that is (by convention) restricted to privileged processes. This
* convention is based on "vouchsafe" principles only. It is only secure
* if you trust the remote host to restrict these ports.
*
* The default range of ports and the high range can be changed by
* sysctl(3). (net.inet.ip.port{hi,low}{first,last}_auto)
*
* Changing those values has bad security implications if you are
* using a a stateless firewall that is allowing packets outside of that
* range in order to allow transparent outgoing connections.
*
* Such a firewall configuration will generally depend on the use of these
* default values. If you change them, you may find your Security
* Administrator looking for you with a heavy object.
*
* For a slightly more orthodox text view on this:
*
* ftp://ftp.isi.edu/in-notes/iana/assignments/port-numbers
*
* port numbers are divided into three ranges:
*
* 0 - 1023 Well Known Ports
* 1024 - 49151 Registered Ports
* 49152 - 65535 Dynamic and/or Private Ports

*
* OS_CLOSED_ENUM(my_type, uint64_t,
* FOO,
* BAR,
* BAZ,
* );
*
* my_type_t mt = 98; // legal
* enum my_type emt = 98; // illegal
*
* But be aware that the underlying enum type's width is subject only to the C
* language's guarantees -- namely that it will be compatible with int, char,
* and unsigned char. It is not safe to rely on the size of this type.
*
* When compiling in ObjC or C++, both of the above assignments are illegal.

* @discussion
* When not building with Objective-C ARC, a block object allocated on or
* copied to the heap must be released with a -[release] message or the
* Block_release() function.
*
* The declaration of a block literal allocates storage on the stack.
* Therefore, this is an invalid construct:
* <code>
* os_block_t block;
* if (x) {
* block = ^{ printf("true\n"); };
* } else {
* block = ^{ printf("false\n"); };
* }
* block(); // unsafe!!!
* </code>
*
* What is happening behind the scenes:
* <code>
* if (x) {
* struct Block __tmp_1 = ...; // setup details
* block = &__tmp_1;
* } else {
* struct Block __tmp_2 = ...; // setup details
* block = &__tmp_2;
* }
* </code>
*
* As the example demonstrates, the address of a stack variable is escaping the
* scope in which it is allocated. That is a classic C bug.
*
* Instead, the block literal must be copied to the heap with the Block_copy()
* function or by sending it a -[copy] message.
