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.

Detailed Description

template<typename _CharT, typename _Traits>

class std::basic_fstream< _CharT, _Traits >" Controlling input and output for files.

Template Parameters:

: _CharT Type of character stream.
_Traits Traits for character type, defaults to char_traits<_CharT>.

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

Member Enumeration Documentation

enum std::ios_base::event [inherited]

The set of events that may be passed to an event callback. erase_event is used during ~ios() and copyfmt(). imbue_event is used during imbue(). copyfmt_event is used during copyfmt().

Definition at line 487 of file ios_base.h.

Constructor & Destructor Documentation

template<typename _CharT , typename _Traits > std::basic_fstream< _CharT, _Traits >::basic_fstream () [inline]

Default constructor. Initializes sb using its default constructor, and passes &sb to the base class initializer. Does not open any files (you haven't given it a filename to open).

Definition at line 889 of file fstream.

template<typename _CharT , typename _Traits > std::basic_fstream< _CharT, _Traits >::basic_fstream (const char * __s, ios_base::openmode __mode = ios_base::in | ios_base::out) [inline], [explicit]

Create an input/output file stream.

Parameters:

: __s Null terminated string specifying the filename.
__mode Open file in specified mode (see std::ios_base).

Tip: When using std::string to hold the filename, you must use .c_str() before passing it to this constructor.

Definition at line 902 of file fstream.

template<typename _CharT , typename _Traits > std::basic_fstream< _CharT, _Traits >::basic_fstream (const std::string & __s, ios_base::openmode __mode = ios_base::in | ios_base::out) [inline], [explicit]

Create an input/output file stream.

Parameters:

: __s Null terminated string specifying the filename.
__mode Open file in specified mode (see std::ios_base).

Definition at line 917 of file fstream.

template<typename _CharT , typename _Traits > std::basic_fstream< _CharT, _Traits >::~basic_fstream () [inline]

The destructor does nothing. The file is closed by the filebuf object, not the formatting stream.

Definition at line 939 of file fstream.

Member Function Documentation

const locale& std::ios_base::_M_getloc () const [inline], [inherited]

Locale access.

Returns:

: A reference to the current locale.

Like getloc above, but returns a reference instead of generating a copy.

template<typename _CharT, typename _Traits> void std::basic_ostream< _CharT, _Traits >::_M_write (const char_type * s, streamsize n) [inline], [inherited]

Core write functionality, without sentry.

Parameters:

: __s The array to insert.
__n Maximum number of characters to insert.

Definition at line 311 of file ostream.

Referenced by std::basic_ostream< _CharT, _Traits >::write().

template<typename _CharT, typename _Traits> bool std::basic_ios< _CharT, _Traits >::bad () const [inline], [inherited]

Fast error checking.

Returns:

: True if the badbit is set.

Note that other iostate flags may also be set.

Definition at line 211 of file basic_ios.h.

template<typename _CharT , typename _Traits > void std::basic_ios< _CharT, _Traits >::clear (iostate __state = goodbit) [inherited]

[Re]sets the error state.

Parameters:

: __state The new state flag(s) to set.

See std::ios_base::iostate for the possible bit values. Most users will not need to pass an argument.

template<typename _CharT , typename _Traits > void std::basic_fstream< _CharT, _Traits >::close () [inline]

Close the file. Calls std::basic_filebuf::close(). If that function fails, failbit is set in the stream's error state.

Definition at line 1041 of file fstream.

template<typename _CharT , typename _Traits > basic_ios< _CharT, _Traits > & std::basic_ios< _CharT, _Traits >::copyfmt (const basic_ios< _CharT, _Traits > & __rhs) [inherited]

Copies fields of __rhs into this.

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().

template<typename _CharT, typename _Traits> bool std::basic_ios< _CharT, _Traits >::eof () const [inline], [inherited]

Fast error checking.

Returns:

Note that other iostate flags may also be set.

Definition at line 190 of file basic_ios.h.

template<typename _CharT, typename _Traits> iostate std::basic_ios< _CharT, _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 222 of file basic_ios.h.

Referenced by std::basic_ios< _CharT, _Traits >::copyfmt(), and std::basic_ios< char, _Traits >::setstate().

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:

1 #include <iostream>
2 #include <fstream>
3 #include <exception>
4 
5 int main()
6 {
7     std::set_terminate (__gnu_cxx::__verbose_terminate_handler);
8 
9     std::ifstream f ("/etc/motd");
10 
11     std::cerr << "Setting badbit;
12     f.setstate (std::ios_base::badbit);
13 
14     std::cerr << "Setting exception mask;
15     f.exceptions (std::ios_base::badbit);
16 }

Definition at line 257 of file basic_ios.h.

template<typename _CharT, typename _Traits> bool std::basic_ios< _CharT, _Traits >::fail () const [inline], [inherited]

Fast error checking.

Returns:

: True if either the badbit or the failbit is set.

Checking the badbit in fail() is historical practice. Note that other iostate flags may also be set.

template<typename _CharT, typename _Traits> char_type std::basic_ios< _CharT, _Traits >::fill () const [inline], [inherited]

Retrieves the empty character.

Returns:

: The current fill character.

It defaults to a space (' ') in the current locale.

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.

template<typename _CharT , typename _Traits > basic_ostream< _CharT, _Traits > & std::basic_ostream< _CharT, _Traits >::flush () [inherited]

Synchronizing the stream buffer.

Returns:

template<typename _CharT , typename _Traits > basic_istream< _CharT, _Traits > & std::basic_istream< _CharT, _Traits >::get (char_type & __c) [inherited]

Simple extraction.

Parameters:

: __c The character in which to store data.

Returns:

: *this

Tries to extract a character and store it in __c. If none are available, sets failbit and returns traits::eof().

Note:

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

template<typename _CharT , typename _Traits > basic_istream< _CharT, _Traits > & std::basic_istream< _CharT, _Traits >::get (char_type * s, streamsize n, char_type __delim) [inherited]

Simple multiple-character extraction.

Parameters:

: __s Pointer to an array.
__n Maximum number of characters to store in __s.
__delim A 'stop' character.

Returns:

: *this

Characters are extracted and stored into __s until one of the following happens:

__n-1 characters are stored
the input sequence reaches EOF
the next character equals __delim, in which case the character is not extracted

If no characters are stored, failbit is set in the stream's error state.

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

Note:

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

template<typename _CharT , typename _Traits > basic_istream< _CharT, _Traits > & std::basic_istream< _CharT, _Traits >::get (__streambuf_type & __sb, char_type __delim) [inherited]

Extraction into another streambuf.

Parameters:

: __sb A streambuf in which to store data.
__delim A 'stop' character.

Returns:

: *this

Characters are extracted and inserted into __sb until one of the following happens:

the input sequence reaches EOF
insertion into the output buffer fails (in this case, the character that would have been inserted is not extracted)
the next character equals __delim (in this case, the character is not extracted)
an exception occurs (and in this case is caught)

If no characters are stored, failbit is set in the stream's error state.

template<typename _CharT , typename _Traits > basic_istream< _CharT, _Traits > & std::basic_istream< _CharT, _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.

Discarding characters.

Parameters:

: __n Number of characters to discard.
__delim A 'stop' character.

Returns:

: *this

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

if __n != std::numeric_limits<int>::max(), __n characters are extracted
the input sequence reaches end-of-file
the next character equals __delim (in this case, the character is extracted); note that this condition will never occur if __delim equals traits::eof().

NB: Provide three overloads, instead of the single function (with defaults) mandated by the Standard: this leads to a better performing implementation, while still conforming to the Standard.

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

Access to integer array.

Parameters:

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.

template<typename _CharT , typename _Traits > basic_ostream< _CharT, _Traits > & std::basic_ostream< _CharT, _Traits >::operator<< (__streambuf_type * __sb) [inherited]

Extracting from another streambuf.

Parameters:

: __sb A pointer to a streambuf

This function behaves like one of the basic arithmetic extractors, in that it also constructs a sentry object and has the same error handling behavior.

If __sb is NULL, the stream will set failbit in its error state.

Characters are extracted from __sb and inserted into *this until one of the following occurs:

the input stream reaches end-of-file,
insertion into the output sequence fails (in this case, the character that would have been inserted is not extracted), or
an exception occurs while getting a character from __sb, which sets failbit in the error state

If the function inserts no characters, failbit is set.

template<typename _CharT , typename _Traits > basic_istream< _CharT, _Traits > & std::basic_istream< _CharT, _Traits >::operator>> (__streambuf_type * __sb) [inherited]

Extracting into another streambuf.

Parameters:

: __sb A pointer to a streambuf

This function behaves like one of the basic arithmetic extractors, in that it also constructs a sentry object and has the same error handling behavior.

If __sb is NULL, the stream will set failbit in its error state.

Characters are extracted from this stream and inserted into the __sb streambuf until one of the following occurs:

the input stream reaches end-of-file,
insertion into the output buffer fails (in this case, the character that would have been inserted is not extracted), or
an exception occurs (and in this case is caught)

If the function inserts no characters, failbit is set.

template<typename _CharT, typename _Traits> 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. For example:

1 std::fstream     foo;         // or some other derived type
2 std::streambuf*  p = .....;
3 
4 foo.ios::rdbuf(p);            // ios == basic_ios<char>

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.

static int std::ios_base::xalloc () [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.
