+/*!
+    \class Q3CString
+    \reentrant
+    \brief The Q3CString class provides an abstraction of the classic C
+    zero-terminated char array (char *).
+
+    \compat
+
+    Q3CString tries to behave like a more convenient \c{const char *}.
+    The price of doing this is that some algorithms will perform
+    badly. For example, append() is O(length()) since it scans for a
+    null terminator. Although you might use Q3CString for text that is
+    never exposed to the user, for most purposes, and especially for
+    user-visible text, you should use QString. QString provides
+    implicit sharing, Unicode and other internationalization support,
+    and is well optimized.
+
+    Note that for the Q3CString methods that take a \c{const char *}
+    parameter the \c{const char *} must either be 0 (null) or not-null
+    and '\0' (NUL byte) terminated; otherwise the results are
+    undefined.
+
+    A Q3CString that has not been assigned to anything is \e null, i.e.
+    both the length and the data pointer is 0. A Q3CString that
+    references the empty string ("", a single '\0' char) is \e empty.
+    Both null and empty Q3CStrings are legal parameters to the methods.
+    Assigning \c{const char *} 0 to Q3CString produces a null Q3CString.
+
+    The length() function returns the length of the string; resize()
+    resizes the string and truncate() truncates the string. A string
+    can be filled with a character using fill(). Strings can be left
+    or right padded with characters using leftJustify() and
+    rightJustify(). Characters, strings and regular expressions can be
+    searched for using find() and findRev(), and counted using
+    contains().
+
+    Strings and characters can be inserted with insert() and appended
+    with append(). A string can be prepended with prepend().
+    Characters can be removed from the string with remove() and
+    replaced with replace().
+
+    Portions of a string can be extracted using left(), right() and
+    mid(). Whitespace can be removed using stripWhiteSpace() and
+    simplifyWhiteSpace(). Strings can be converted to uppercase or
+    lowercase with upper() and lower() respectively.
+
+    Strings that contain numbers can be converted to numbers with
+    toShort(), toInt(), toLong(), toULong(), toFloat() and toDouble().
+    Numbers can be converted to strings with setNum().
+
+    Many operators are overloaded to work with Q3CStrings. Q3CString
+    also supports some more obscure functions, e.g. sprintf(),
+    setStr() and setExpand().
+
+    \sidebar Note on Character Comparisons
+
+    In Q3CString the notion of uppercase and lowercase and of which
+    character is greater than or less than another character is locale
+    dependent. This affects functions which support a case insensitive
+    option or which compare or lowercase or uppercase their arguments.
+    Case insensitive operations and comparisons will be accurate if
+    both strings contain only ASCII characters. (If \c $LC_CTYPE is
+    set, most Unix systems do "the right thing".) Functions that this
+    affects include contains(), find(), findRev(), \l operator<(), \l
+    operator<=(), \l operator>(), \l operator>=(), lower() and
+    upper().
+
+    This issue does not apply to \l{QString}s since they represent
+    characters using Unicode.
+    \endsidebar
+
+    Performance note: The Q3CString methods for QRegExp searching are
+    implemented by converting the Q3CString to a QString and performing
+    the search on that. This implies a deep copy of the Q3CString data.
+    If you are going to perform many QRegExp searches on a large
+    Q3CString, you will get better performance by converting the
+    Q3CString to a QString yourself, and then searching in the QString.

+/*!
+    \class Q3DeepCopy
+    \brief The Q3DeepCopy class is a template class which ensures that
+    implicitly shared and explicitly shared classes reference unique
+    data.
+
+    \reentrant
+
+    \compat
+
+    Normally, shared copies reference the same data to optimize memory
+    use and for maximum speed. In the example below, \c s1, \c s2, \c
+    s3, \c s4 and \c s5 share data.
+
+    \snippet doc/src/snippets/code/src_qt3support_tools_q3deepcopy.cpp 0
+
+    Q3DeepCopy can be used several ways to ensure that an object
+    references unique, unshared data. In the example below, \c s1, \c
+    s2 and \c s5 share data, while neither \c s3 nor \c s4 share data.
+    \snippet doc/src/snippets/code/src_qt3support_tools_q3deepcopy.cpp 1
+
+    In the example below, \c s1, \c s2 and \c s5 share data, and \c s3
+    and \c s4 share data.
+    \snippet doc/src/snippets/code/src_qt3support_tools_q3deepcopy.cpp 2
+
+    Q3DeepCopy can also provide safety in multithreaded applications
+    that use shared classes. In the example below, the variable \c
+    global_string is used safely since the data contained in \c
+    global_string is always a deep copy. This ensures that all threads
+    get a unique copy of the data, and that any assignments to \c
+    global_string will result in a deep copy.
+
+    \snippet doc/src/snippets/code/src_qt3support_tools_q3deepcopy.cpp 3
+
+    \warning It is the application developer's responsibility to
+    protect the object shared across multiple threads.
+
+    The examples above use QString, which is an implicitly shared
+    class. The behavior of Q3DeepCopy is the same when using explicitly
+    shared classes like QByteArray.
+
+    Currently, Q3DeepCopy works with the following classes:
+    \list
+    \i QMemArray (including subclasses like QByteArray and QCString)
+    \i QMap
+    \i QString
+    \i QValueList (including subclasses like QStringList and QValueStack)
+    \i QValueVector
+    \endlist
+
+    \sa \link threads.html Thread Support in Qt \endlink

+
+  \internal
+
+  Q3LNode is a doubly-linked list node. It has three pointers:
+  \list 1
+  \i Pointer to the previous node.
+  \i Pointer to the next node.
+  \i Pointer to the actual data.
+  \endlist
+
+  It might sometimes be practical to have direct access to the list nodes
+  in a Q3PtrList, but it is seldom required.
+
+  Be very careful if you want to access the list nodes. The heap can
+  easily get corrupted if you make a mistake.

+
+  Q3GList is a strictly internal class that acts as a base class for
+  several collection classes; Q3PtrList, Q3PtrQueue and Q3PtrStack.
+
+  Q3GList has some virtual functions that can be reimplemented to
+  customize the subclasses, namely compareItems(), read() and
+  write. Normally, you do not have to reimplement any of these
+  functions.  If you still want to reimplement them, see the QStrList

+  collection classes.
+
+  \internal
+
+  Q3GVector is an internal class that acts as a base class for the
+  Q3PtrVector collection class.
+
+  Q3GVector has some virtual functions that may be reimplemented in
+  subclasses to customize behavior.
+
+  \list
+  \i compareItems() compares two collection/vector items.
+  \i read() reads a collection/vector item from a QDataStream.
+  \i write() writes a collection/vector item to a QDataStream.
+  \endlist

+  This virtual function compares two list items.
+
+  Returns:
+  <ul>
+  <li> 0 if \a d1 == \a d2
+  <li> non-zero if \a d1 != \a d2
+  </ul>
+
+  This function returns \e int rather than \e bool so that
+  reimplementations can return one of three values and use it to sort
+  by:
+  <ul>
+  <li> 0 if \a d1 == \a d2
+  <li> \> 0 (positive integer) if \a d1 \> \a d2
+  <li> \< 0 (negative integer) if \a d1 \< \a d2
+  </ul>
+
+  The Q3PtrVector::sort() and Q3PtrVector::bsearch() functions require that
+  compareItems() is implemented as described here.
+
+  This function should not modify the vector because some const
+  functions call compareItems().

+    \class Q3PtrCollection
+    \reentrant
+    \brief The Q3PtrCollection class is the base class of most pointer-based Qt collections.
+
+    \compat
+
+    The Q3PtrCollection class is an abstract base class for the Qt
+    collection classes QDict, Q3PtrList,
+    etc.
+
+    A Q3PtrCollection only knows about the number of objects in the
+    collection and the deletion strategy (see setAutoDelete()).
+
+    A collection is implemented using the \c Item (generic collection
+    item) type, which is a \c void*. The template classes that create
+    the real collections cast the \c Item to the required type.
+*/
+
+
+/*!
+    \typedef Q3PtrCollection::Item
+
+    This type is the generic "item" in a Q3PtrCollection.
+*/
+
+
+/*!
+    \fn Q3PtrCollection::Q3PtrCollection()
+
+    Constructs a collection. The constructor is protected because
+    Q3PtrCollection is an abstract class.
+*/
+
+/*!
+    \fn Q3PtrCollection::Q3PtrCollection( const Q3PtrCollection & source )

+/*!
+    \class Q3Semaphore
+    \threadsafe
+    \brief The Q3Semaphore class provides a robust integer semaphore.
+
+    \compat
+
+    A Q3Semaphore can be used to serialize thread execution, in a
+    similar way to a QMutex. A semaphore differs from a mutex, in
+    that a semaphore can be accessed by more than one thread at a
+    time.
+
+    For example, suppose we have an application that stores data in a
+    large tree structure. The application creates 10 threads
+    (commonly called a thread pool) to perform searches on the tree.
+    When the application searches the tree for some piece of data, it
+    uses one thread per base node to do the searching. A semaphore
+    could be used to make sure that two threads don't try to search
+    the same branch of the tree at the same time.
+
+    A non-computing example of a semaphore would be dining at a
+    restaurant. A semaphore is initialized to have a maximum count
+    equal to the number of chairs in the restaurant. As people
+    arrive, they want a seat. As seats are filled, the semaphore is
+    accessed, once per person. As people leave, the access is
+    released, allowing more people to enter. If a party of 10 people
+    want to be seated, but there are only 9 seats, those 10 people
+    will wait, but a party of 4 people would be seated (taking the
+    available seats to 5, making the party of 10 people wait longer).
+
+    When a semaphore is created it is given a number which is the
+    maximum number of concurrent accesses it will permit. This amount
+    may be changed using operator++(), operator--(), operator+=() and
+    operator-=(). The number of accesses allowed is retrieved with
+    available(), and the total number with total(). Note that the
+    incrementing functions will block if there aren't enough available
+    accesses. Use tryAccess() if you want to acquire accesses without
+    blocking.

+    \class Q3Signal
+    \brief The Q3Signal class can be used to send signals for classes
+    that don't inherit QObject.
+
+    \compat
+
+    If you want to send signals from a class that does not inherit
+    QObject, you can create an internal Q3Signal object to emit the
+    signal. You must also provide a function that connects the signal
+    to an outside object slot.  This is how we used to implement
+    signals in Qt 3's QMenuData class, which was not a QObject. In Qt
+    4, menus contain actions, which are QObjects.
+
+    In general, we recommend inheriting QObject instead. QObject
+    provides much more functionality.
+
+    You can set a single QVariant parameter for the signal with
+    setValue().
+
+    Note that QObject is a \e private base class of Q3Signal, i.e. you
+    cannot call any QObject member functions from a Q3Signal object.
+
+    Example:
