 /*!
     \class QCString qcstring.h
     \reentrant
     \brief The QCString class provides an abstraction of the classic C
     zero-terminated char array (char *).
 
     \ingroup text
     \ingroup collection
     \ingroup tools
     \ingroup shared
 
     QCString inherits QByteArray, which is defined as
     QMemArray\<char\>. Since QCString is a QMemArray, it uses \link
     shclass.html explicit sharing\endlink with a reference count.
 
     QCString 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 QCString 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 QCString 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 QCString that has not been assigned to anything is \e null, i.e.
     both the length and the data pointer is 0. A QCString that
     references the empty string ("", a single '\0' char) is \e empty.
     Both null and empty QCStrings are legal parameters to the methods.
     Assigning \c{const char *} 0 to QCString produces a null QCString.
 
     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 QCStrings. QCString
     also supports some more obscure functions, e.g. sprintf(),
     setStr() and setExpand().
 
     \target asciinotion
     \sidebar Note on Character Comparisons
 
     In QCString 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 QCString methods for QRegExp searching are
     implemented by converting the QCString to a QString and performing
     the search on that. This implies a deep copy of the QCString data.
     If you are going to perform many QRegExp searches on a large
     QCString, you will get better performance by converting the
     QCString to a QString yourself, and then searching in the QString.

     Implemented as a call to the native vsprintf() (see the manual for

     string is resized back to its actual length before sprintf()
     returns.

     \warning All vsprintf() implementations will write past the end of
     the target string (*this) if the \a format specification and
     arguments happen to be longer than the target string, and some
     will also fail if the target string is longer than some arbitrary
