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.

 Basic arithmetic extractors.

Unformatted Input Functions
All the unformatted 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 true. 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.

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

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.

Arithmetic Inserters
All the operator<< functions (aka formatted output functions) have some common behavior. Each starts by constructing a temporary object of type std::basic_ostream::sentry. This can have 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 generate whatever data is appropriate for the type of the argument.

If an exception is thrown during insertion, 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.

Unformatted Output Functions
All the unformatted output functions have some common behavior. Each starts by constructing a temporary object of type std::basic_ostream::sentry. 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 generate whatever data is appropriate for the type of the argument.

If an exception is thrown during insertion, ios_base::badbit will be turned on in the stream's error state. If badbit is on in the stream's exceptions mask, the exception will be rethrown without completing its actions.

__ostream_typewrite (const char_type *s, streamsize n)
 Character string insertion.

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.

Default constructor starts with an empty string buffer.

Parameters:
mode Whether the buffer can read, or write, or both.

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 flage 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()
  {
      std::set_terminate (__gnu_cxx::__verbose_terminate_handler);
  
      std::ifstream f ("/etc/motd");
  
      std::cerr << "Setting badbit\n";
      f.setstate (std::ios_base::badbit);
  
      std::cerr << "Setting exception mask\n";

template<typename CharT, typename Traits>
iostate std::basic_ios< CharT, Traits >::exceptions (  )  const [inline, inherited]

Throwing exceptions on errors.

Returns:

This changes nothing in the stream. See the one-argument version of exceptions(iostate) for the meaning of the return value.

Fast error checking.

char_type std::basic_ios< CharT, Traits >::fill ( char_type  ch  )  [inline, inherited]

Sets a new "empty" character.

Parameters:
ch The new character.
Returns:
The previous fill character.
The fill character is used to fill out space when P+ characters have been requested (e.g., via setw), Q characters are actually used, and Q<P. It defaults to a space (' ') in the current locale.

basic_istream< CharT, Traits > & std::basic_istream< CharT, Traits >::getline ( char_type s,

) [inherited]

String extraction.

Parameters:
s A character array in which to store the data.
n Maximum number of characters to extract.
delim A "stop" character.
Returns:
*this
Extracts and stores characters into s until one of the following happens. Note that these criteria are required to be tested in the order listed here, to allow an input line to exactly fill the s array without setting failbit.

  1. the input sequence reaches end-of-file, in which case eofbit is set in the stream error state
  2. the next character equals delim, in which case the character is extracted (and therefore counted in gcount()) but not stored
  3. n-1 characters are stored, in which case failbit is set in the stream error state

If no characters are extracted, failbit is set. (An empty line of input should therefore not cause failbit to be set.)

In any case, a null character is stored in the next location in the array.

template<typename CharT, typename Traits>
basic_istream< CharT, Traits > & std::basic_istream< CharT, Traits >::putback ( char_type  c  )  [inherited]

Unextracting a single character.

Parameters:
c The character to push back into the input stream.
Returns:
*this
If rdbuf() is not null, calls rdbuf()->sputbackc(c).

If rdbuf() is null or if sputbackc() fails, sets badbit in the error state.

Note:
Since no characters are extracted, the next call to gcount() will return 0, as required by DR 60.

basic_streambuf< CharT, Traits > * std::basic_ios< CharT, Traits >::rdbuf ( basic_streambuf< CharT, Traits > *  sb  )  [inherited]

Changing the underlying buffer.

Parameters:
sb The new stream buffer.
Returns:
The previous stream buffer.
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.

Extraction until the buffer is exhausted, but no more.

Parameters:

Returns:

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:

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