[section Overview]
The header <boost/utility/ostream_string.hpp> provides the function template
`boost::ostream_string` for formatted output that satisfies the requirements of
\[ostream.formatted.reqmts\].
[endsect]
[section Examples]
The inserter for class template `basic_string_view` could be implemented as
follows:
```
template<class charT, class traits>
std::basic_ostream<charT, traits>&
operator<<(std::basic_ostream<charT, traits>& os,
const basic_string_view<charT, traits>& str)
{
return boost::ostream_string(os, str.data(), str.size());
}
```
[endsect]
[section Reference]
```
namespace boost {
template<class charT, class traits>
std::basic_ostream<charT, traits>&
ostream_string(std::basic_ostream<charT, traits>& os,
const charT* data, std::size_t size);
} /* boost */
```
[heading Free functions]
[variablelist
[[`template<class charT, class traits> std::basic_ostream<charT, traits>&
ostream_string(std::basic_ostream<charT, traits>& os, const charT* data,
std::size_t size);`]
[[variablelist
[[Effects]
[Behaves like a formatted inserter (as described in
\[ostream.formatted.reqmts\]) of `os`. Creates a character sequence `seq` of
`size` characters starting at `data`, each widened using `os.widen()`
(\[basic.ios.members\]). Determines padding for `seq` as described in
\[ostream.formatted.reqmts\]. Inserts `seq` into `os`. Calls `width(0)`.]]
[[Returns][`os`.]]]]]]
[endsect]
[section History]
[heading boost 1.71]
* Glen Fernandes updated the implementation of the `basic_string_ref` and
`basic_string_view` stream insertion operators to write directly to the
`basic_streambuf` and refactored that functionality into this common utility.
