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.

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.

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

Copies fields of __rhs into this. Parameters:

Returns:

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().

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

template<typename _CharT, typename _Traits> void std::basic_ios< _CharT, _Traits >::exceptions (iostate__except) [inline], [inherited]¶

Throwing exceptions on errors. Parameters:

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 badbit0;


    f.setstate (std::ios_base::badbit);


    std::cerr << 'Setting exception mask0;


    f.exceptions (std::ios_base::badbit);
}

If rdbuf() is a null pointer, changes nothing.

long& std::ios_base::iword (int__ix) [inline], [inherited]¶

Access to integer array. Parameters:

Returns:

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

Extracting from another streambuf. Parameters:

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.

void*& std::ios_base::pword (int__ix) [inline], [inherited]¶

Access to void pointer array. Parameters:

Returns:

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.

template<typename _CharT, typename _Traits> basic_streambuf< _CharT, _Traits > * basic_ios< _CharT, _Traits >::rdbuf (basic_streambuf< _CharT, _Traits > *__sb) [inherited]¶

Changing the underlying buffer. Parameters:

Returns:

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:

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.
