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.

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.

__istream_type& std::basic_istream< char , Traits >::getline ( char_type s,
streamsize  n,
char_type  __delim 
) [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.

__istream_type& std::basic_istream< char , Traits >::getline ( char_type s,
streamsize  n 
) [inline, inherited]

String extraction.

Parameters:
s A character array in which to store the data.

Extracts characters and throws them away until one of the following happens:

int_type std::basic_istream< char , Traits >::peek ( void   )  [inherited]

Looking ahead in the stream.

Returns:
The next character, or eof().
If, after constructing the sentry object, good() is false, returns traits::eof(). Otherwise reads but does not extract the next input character.

__istream_type& std::basic_istream< char , Traits >::read ( char_type s,
streamsize  n 
) [inherited]

Extraction without delimiters.

Parameters:
s A character array.
n Maximum number of characters to store.
Returns:
*this
If the stream state is good(), extracts characters and stores them into s until one of the following happens:

Note:
This function is not overloaded on signed char and unsigned char.

streamsize std::basic_istream< char , 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:

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

__istream_type& std::basic_istream< char , 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.

__istream_type& std::basic_istream< char , Traits >::unget ( void   )  [inherited]

Unextracting the previous character.

Returns:
*this
If rdbuf() is not null, calls rdbuf()->sungetc(c).

If rdbuf() is null or if sungetc() 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.

int std::basic_istream< char , Traits >::sync ( void   )  [inherited]

Synchronizing the stream buffer.

Returns:
0 on success, -1 on failure
If rdbuf() is a null pointer, returns -1.

Otherwise, calls rdbuf()->pubsync(), and if that returns -1, sets badbit and returns -1.

Otherwise, returns 0.

Note:
This function does not count the number of characters extracted, if any, and therefore does not affect the next call to gcount().

pos_type std::basic_istream< char , Traits >::tellg ( void   )  [inherited]

Getting the current read position.

Returns:
A file position object.
If fail() is not false, returns pos_type(-1) to indicate failure. Otherwise returns rdbuf()->pubseekoff(0,cur,in).

Note:
This function does not count the number of characters extracted, if any, and therefore does not affect the next call to gcount().

__istream_type& std::basic_istream< char , Traits >::seekg ( pos_type   )  [inherited]

Changing the current read position.

Parameters:
pos A file position object.
Returns:
*this
If fail() is not true, calls rdbuf()->pubseekpos(pos). If that function fails, sets failbit.

Note:
This function does not count the number of characters extracted, if any, and therefore does not affect the next call to gcount().

__istream_type& std::basic_istream< char , Traits >::seekg ( off_type  ,
ios_base::seekdir   
) [inherited]

Changing the current read position.

Parameters:
off A file offset object.
dir The direction in which to seek.
Returns:
*this
If fail() is not true, calls rdbuf()->pubseekoff(off,dir). If that function fails, sets failbit.

Note:
This function does not count the number of characters extracted, if any, and therefore does not affect the next call to gcount().

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

Throwing exceptions on errors.

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

Definition at line 208 of file basic_ios.h.

void std::basic_ios< char , 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);

basic_ostream<char , Traits >* std::basic_ios< char , Traits >::tie (  )  const [inline, inherited]

Fetches the current tied stream.

Returns:
A pointer to the tied stream, or NULL if the stream is not tied.
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.

Definition at line 281 of file basic_ios.h.

basic_ostream<char , Traits >* std::basic_ios< char , Traits >::tie ( basic_ostream< char , Traits > *  __tiestr  )  [inline, inherited]

Ties this stream to an output stream.

Parameters:
tiestr The output stream.
Returns:
The previously tied output stream, or NULL if the stream was not tied.
This sets up a new tie; see tie() for more.

Definition at line 293 of file basic_ios.h.

basic_streambuf<char , Traits >* std::basic_ios< char , Traits >::rdbuf ( basic_streambuf< char , 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. For example:

  std::fstream     foo;         // or some other derived type
  std::streambuf*  p = .....;

  foo.ios::rdbuf(p);            // ios == basic_ios<char>

basic_ios& std::basic_ios< char , Traits >::copyfmt ( const basic_ios< char, Traits > &  __rhs  )  [inherited]

Parameters:
__rhs The source values for the copies.
Returns:
Reference to this object.
All fields of __rhs are copied into this object except that rdbuf() and rdstate() remain unchanged. All values in the pword and iword arrays are copied. Before copying, each callback is invoked with erase_event. After copying, each (new) callback is invoked with copyfmt_event. The final step is to copy exceptions().

char_type std::basic_ios< char , Traits >::fill (  )  const [inline, inherited]

Retreives the "empty" character.

Returns:
The current fill character.
It defaults to a space (' ') in the current locale.

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.

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.

Definition at line 139 of file ios.cc.

long& std::ios_base::iword ( int  __ix  )  [inline, inherited]

Access to integer array.

Parameters:
__ix Index into the array.
Returns:
A reference to an integer associated with the index.
The iword function provides access to an array of integers that can be used for any purpose. The array grows as required to hold the supplied index. All integers in the array 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.

Definition at line 723 of file ios_base.h.

void*& std::ios_base::pword ( int  __ix  )  [inline, inherited]

Access to void pointer array.

Parameters:
__ix Index into the array.
Returns:
A reference to a void* associated with the index.
The pword function provides access to an array of pointers that can be used for any purpose. The array grows as required to hold the supplied index. All pointers in the array 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.
