Detailed Description

template<typename _CharT, typename _Traits>
class std::basic_ostream< _CharT, _Traits >

Controlling output.

This is the base class for all output streams. It provides text formatting of all builtin types, and communicates with any class derived from basic_streambuf to do the actual output.

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.

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.

Constructor & Destructor Documentation

template<typename _CharT, typename _Traits>
std::basic_ostream< _CharT, _Traits >::basic_ostream ( __streambuf_type *  __sb  )  [inline, explicit]

Base constructor.

This ctor is almost never called by the user directly, rather from derived classes' initialization lists, which pass a pointer to their own stream buffer.

Definition at line 86 of file ostream.

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

Base destructor.

This does very little apart from providing a virtual base dtor.

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>
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()
  {
      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";
      f.exceptions (std::ios_base::badbit);
  }

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

Fast error checking.

Returns:

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

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.

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.

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:

If the function inserts no characters, failbit is set.

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.

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:

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

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

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.
