FOUR_CHAR_CODE
This conditional is deprecated. It was used to work around a bug in one obscure compiler that did not pack multiple characters in single quotes rationally.
It was never intended for endian swapping.
FOUR_CHAR_CODE('abcd') - Convert a four-char-code to the correct 32-bit value
TYPE_*
These conditionals specify whether the compiler supports particular types.
TYPE_LONGLONG - Compiler supports "long long" 64-bit integers
TYPE_EXTENDED - Compiler supports "extended" 80/96 bit floating point
TYPE_LONGDOUBLE_IS_DOUBLE - Compiler implements "long double" same as "double"
FUNCTION_*
These conditionals specify whether the compiler supports particular language extensions
to function prototypes and definitions.
FUNCTION_PASCAL - Compiler supports "pascal void Foo()"
FUNCTION_DECLSPEC - Compiler supports "__declspec(xxx) void Foo()"
FUNCTION_WIN32CC - Compiler supports "void __cdecl Foo()" and "void __stdcall Foo()"

Under MacOS, the classic 68k runtime has two calling conventions: pascal or C
Under Win32, there are two calling conventions: __cdecl or __stdcall
Headers and implementation files can use the following macros to make their
source more portable by hiding the calling convention details:
EXTERN_API*
These macros are used to specify the calling convention on a function prototype.
EXTERN_API - Classic 68k: pascal, Win32: __cdecl
EXTERN_API_C - Classic 68k: C, Win32: __cdecl
EXTERN_API_STDCALL - Classic 68k: pascal, Win32: __stdcall
EXTERN_API_C_STDCALL - Classic 68k: C, Win32: __stdcall
DEFINE_API*
These macros are used to specify the calling convention on a function definition.
DEFINE_API - Classic 68k: pascal, Win32: __cdecl
DEFINE_API_C - Classic 68k: C, Win32: __cdecl
DEFINE_API_STDCALL - Classic 68k: pascal, Win32: __stdcall
DEFINE_API_C_STDCALL - Classic 68k: C, Win32: __stdcall
CALLBACK_API*
These macros are used to specify the calling convention of a function pointer.
CALLBACK_API - Classic 68k: pascal, Win32: __stdcall
CALLBACK_API_C - Classic 68k: C, Win32: __stdcall
CALLBACK_API_STDCALL - Classic 68k: pascal, Win32: __cdecl
CALLBACK_API_C_STDCALL - Classic 68k: C, Win32: __cdecl

OLDROUTINENAMES - "Old" names for Macintosh system calls are allowed in source code.
(e.g. DisposPtr instead of DisposePtr). The names of system routine
are now more sensitive to change because CFM binds by name. In the
past, system routine names were compiled out to just an A-Trap.
Macros have been added that each map an old name to its new name.
This allows old routine names to be used in existing source files,
but the macros only work if OLDROUTINENAMES is true. This support
will be removed in the near future. Thus, all source code should
be changed to use the new names! You can set OLDROUTINENAMES to false
to see if your code has any old names left in it.

The following macros isolate the use of 68K inlines in function prototypes.
On the Mac OS under the Classic 68K runtime, function prototypes were followed

of a JSR. Under Classic 68K on the Mac OS, this macro will put the opcodes
in the right syntax. For all other OS's and runtimes the macro suppress the opcodes.

TARGET_CARBON - default: false. Switches all of the above as described. Overrides all others
- NOTE: If you set TARGET_CARBON to 1, then the other switches will be setup by
ConditionalMacros, and should not be set manually.
If you wish to do development for pre-Carbon Systems, you can set the following:
OPAQUE_TOOLBOX_STRUCTS - default: false. True for Carbon builds, hides struct fields.
OPAQUE_UPP_TYPES - default: false. True for Carbon builds, UPP types are unique and opaque.
ACCESSOR_CALLS_ARE_FUNCTIONS - default: false. True for Carbon builds, enables accessor functions.
CALL_NOT_IN_CARBON - default: true. False for Carbon builds, hides calls not supported in Carbon.
Specifically, if you are building a non-Carbon application (one that links against InterfaceLib)
but you wish to use some of the accessor functions, you can set ACCESSOR_CALLS_ARE_FUNCTIONS to 1
and link with CarbonAccessors.o, which implements just the accessor functions. This will help you
preserve source compatibility between your Carbon and non-Carbon application targets.
MIXEDMODE_CALLS_ARE_FUNCTIONS - deprecated.

kInvalidID KernelID: NULL is for pointers as kInvalidID is for ID's
kVariableLengthArray array bounds: variable length array
Note: kVariableLengthArray was used in array bounds to specify a variable length array,
usually the last field in a struct. Now that the C language supports
the concept of flexible array members, you can instead use:
struct BarList
{
short listLength;
Bar elements[];
};
However, this changes the semantics somewhat, as sizeof( BarList ) contains
no space for any of the elements, so to allocate a list with space for
the count elements
struct BarList* l = (struct BarList*) malloc( sizeof(BarList) + count * sizeof(Bar) );

String Types and Unicode Types
UnicodeScalarValue, A complete Unicode character in UTF-32 format, with
UTF32Char values from 0 through 0x10FFFF (excluding the surrogate
range 0xD800-0xDFFF and certain disallowed values).
UniChar, A 16-bit Unicode code value in the default UTF-16 format.
UTF16Char UnicodeScalarValues 0-0xFFFF are expressed in UTF-16
format using a single UTF16Char with the same value.
UnicodeScalarValues 0x10000-0x10FFFF are expressed in
UTF-16 format using a pair of UTF16Chars - one in the
high surrogate range (0xD800-0xDBFF) followed by one in
the low surrogate range (0xDC00-0xDFFF). All of the
characters defined in Unicode versions through 3.0 are
in the range 0-0xFFFF and can be expressed using a single
UTF16Char, thus the term "Unicode character" generally
refers to a UniChar = UTF16Char.
UTF8Char An 8-bit code value in UTF-8 format. UnicodeScalarValues
0-0x7F are expressed in UTF-8 format using one UTF8Char
with the same value. UnicodeScalarValues above 0x7F are
expressed in UTF-8 format using 2-4 UTF8Chars, all with
values in the range 0x80-0xF4 (UnicodeScalarValues
0x100-0xFFFF use two or three UTF8Chars,
UnicodeScalarValues 0x10000-0x10FFFF use four UTF8Chars).
UniCharCount A count of UTF-16 code values in an array or buffer.
StrNNN Pascal string holding up to NNN bytes
StringPtr Pointer to a pascal string
StringHandle Pointer to a StringPtr
ConstStringPtr Pointer to a read-only pascal string
ConstStrNNNParam For function parameters only - means string is const
CStringPtr Pointer to a C string (in C: char*)
ConstCStringPtr Pointer to a read-only C string (in C: const char*)
Note: The length of a pascal string is stored as the first byte.
A pascal string does not have a termination byte.
A pascal string can hold at most 255 bytes of data.
The first character in a pascal string is offset one byte from the start of the string.
A C string is terminated with a byte of value zero.
A C string has no length limitation.
The first character in a C string is the zeroth byte of the string.

* @const DISPATCH_BLOCK_NO_QOS_CLASS
* Flag indicating that a dispatch block object should be not be assigned a QOS
* class. If invoked directly, the block object will be executed with the QOS
* class of the calling thread. If the block object is submitted to a queue,
* this replaces the default behavior of associating the submitted block

* 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
* for asynchronous execution and has no effect when the dispatch block object
* is invoked directly. It is ignored if DISPATCH_BLOCK_ENFORCE_QOS_CLASS is

* 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.
*

*
* @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 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

* - 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
* results in NULL being returned.

* @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>
* dispatch_block_t block;
* if (x) {
* block = ^{ printf("true\n"); };
* } else {
* block = ^{ printf("false\n"); };
* }
* block(); // unsafe!!!

* <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.

* is not allowed (see dispatch_activate() and dispatch_set_target_queue()).

* '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
* strictly observe the provided 'leeway' value even if it is smaller than the
* current lower limit. Note that a minimal amount of delay is to be expected
* even if this flag is specified.
*
* The 'start' argument also determines which clock will be used for the timer:
* 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
* Apple platforms). If 'start' was created with dispatch_walltime(3), the
* timer is based on gettimeofday(3).
*
* Calling this function has no effect if the timer source has already been
* canceled.
*
* @param start
* The start time of the timer. See dispatch_time() and dispatch_walltime()
* for more information.
*
* @param interval
* The nanosecond interval for the timer. Use DISPATCH_TIME_FOREVER for a
* one-shot timer.
*
* @param leeway
* The nanosecond leeway for the timer.

* @function launch_activate_socket
*
* @abstract
* Retrieves the file descriptors for sockets specified in the process'
* launchd.plist(5).
*
* @param name
* The name of the socket entry in the service's Sockets dictionary.
*
* @param fds
* On return, this parameter will be populated with an array of file
* descriptors. One socket can have many descriptors associated with it
* depending on the characteristics of the network interfaces on the system.
* The descriptors in this array are the results of calling getaddrinfo(3) with
* the parameters described in launchd.plist(5).
*
* The caller is responsible for calling free(3) on the returned pointer.
*
* @param cnt
* The number of file descriptor entries in the returned array.
*
* @result
* On success, zero is returned. Otherwise, an appropriate POSIX-domain is
* returned. Possible error codes are:
*
* ENOENT -> There was no socket of the specified name owned by the caller.
* ESRCH -> The caller is not a process managed by launchd.
* EALREADY -> The socket has already been activated by the caller.

*
* This lock must be unlocked from the same thread that locked it, attempts to
* unlock from a different thread will cause an assertion aborting the process.

* Replacement for the deprecated OSSpinLock. Does not spin on contention but
* waits in the kernel to be woken up by an unlock.
*
* As with OSSpinLock there is no attempt at fairness or lock ordering, e.g. an
* unlocker can potentially immediately reacquire the lock before a woken up
* waiter gets an opportunity to attempt to acquire the lock. This may be
* advantageous for performance reasons, but also makes starvation of waiters a

* @function os_workgroup_cancel

* This API invalidates a workgroup and indicates to the system that the
* workload is no longer relevant to the caller.
*
* No new work should be initiated for a cancelled workgroup and
* work that is already underway should periodically check for
* cancellation with os_workgroup_testcancel and initiate cleanup if needed.
*
* Threads currently in the workgroup continue to be tracked together but no
* new threads may join this workgroup - the only possible operation allowed is
* to leave the workgroup. Other actions may have undefined behavior or
* otherwise fail.
*
* This API is idempotent. Cancellation is local to the workgroup object
* it is called on and does not affect other workgroups.
*
* @param wg
* The workgroup that that the thread would like to cancel
