       Arithmetic Extractors
       All the operator>> functions (aka formatted input functions) have some common behavior.
       Each starts by constructing a temporary object of type std::basic_istream::sentry with the
       second argument (noskipws) set to false. This has several effects, concluding with the
       setting of a status flag; see the sentry documentation for more.

       If the sentry status is good, the function tries to extract whatever data is appropriate
       for the type of the argument.

       If an exception is thrown during extraction, ios_base::badbit will be turned on in the
       stream's error state without causing an ios_base::failure to be thrown. The original
       exception will then be rethrown.

       If the sentry status is good, the function tries to extract whatever data is appropriate

       The number of characters extracted is stored for later retrieval by gcount().

Detailed Description

   template<typename _CharT, typename _Traits, typename _Alloc>class std::basic_stringstream<
       _CharT, _Traits, _Alloc >
       Controlling input and output for std::string.

       This class supports reading from and writing to objects of type std::basic_string, using
       the inherited functions from std::basic_iostream. To control the associated sequence, an
       instance of std::basic_stringbuf is used, which this page refers to as sb.

   template<typename _CharT, typename _Traits> void std::basic_ios< _CharT, _Traits >::exceptions
       (iostate__except) [inline, inherited]
       Throwing exceptions on errors. Parameters:
           except The new exceptions mask.

       By default, error flags are set silently. You can set an exceptions mask for each stream;
       if a bit in the mask becomes set in the error flags, then an exception of type
       std::ios_base::failure is thrown.

       If the error flag is already set when the exceptions mask is added, the exception is
       immediately thrown. Try running the following under GCC 3.1 or later:

         #include <iostream>
         #include <fstream>
         #include <exception>

         int main()
         {

       The iword function provides access to an array of integers that can be used for any

       are initialized to 0.

       The implementation reserves several indices. You should use xalloc to obtain an index that

       · an exception occurs while getting a character from sb, which sets failbit in the error
         state

       The pword function provides access to an array of pointers that can be used for any

       are initialized to 0.

       The implementation reserves several indices. You should use xalloc to obtain an index that
       is safe to use. Also note that since the array can grow dynamically, it is not safe to
       hold onto the reference.

       Associates a new buffer with the current stream, and clears the error state.

       Due to historical accidents which the LWG refuses to correct, the I/O library suffers from
       a design error: this function is hidden in derived classes by overrides of the zero-
       argument rdbuf(), which is non-virtual for hysterical raisins. As a result, you must use
       explicit qualifications to access this function via any derived class. For example:

         std::streambuf*  p = .....;

   template<typename _CharT , typename _Traits > streamsize std::basic_istream< _CharT, _Traits
       >::readsome (char_type *__s, streamsize__n) [inherited]
       Extraction until the buffer is exhausted, but no more. Parameters:
           s A character array.
           n Maximum number of characters to store.

       Returns:
           The number of characters extracted.

       Extracts characters and stores them into s depending on the number of characters remaining
       in the streambuf's buffer, rdbuf()->in_avail(), called A here:

       · if A == -1, sets eofbit and extracts no characters

       · if A == 0, extracts no characters

       · if A > 0, extracts min(A,n)

       The goal is to empty the current buffer, and to not request any more from the external
       input sequence controlled by the streambuf.

       A stream may be tied (or synchronized) to a second output stream. When this stream
       performs any I/O, the tied stream is first flushed. For example, std::cin is tied to
       std::cout.

   static int std::ios_base::xalloc ()  throw () [static, inherited]
       Access to unique indices. Returns:
           An integer different from all previous calls.

       This function returns a unique integer every time it is called. It can be used for any
       purpose, but is primarily intended to be a unique index for the iword and pword functions.
       The expectation is that an application calls xalloc in order to obtain an index in the
       iword and pword arrays that can be used without fear of conflict.

       The implementation maintains a static variable that is incremented and returned on each
       invocation. xalloc is guaranteed to return an index that is safe to use in the iword and
       pword arrays.
