Discussion:
The recent draft (as well as the original proposal n2072) uses an operational semantic for get_money ([ext.manip]/4) and put_money ([ext.manip]/6), which uses
istreambuf_iterator<charT>
and
ostreambuf_iterator<charT>
resp, instead of the iterator instances, with explicitly provided traits argument (The operational semantic defined by f is also traits dependent). This is an obvious oversight because both *stream_buf c'tors expect a basic_streambuf<charT,traits> as argument.
The same problem occurs within the get_time and put_time semantic where additional to the problem we have an editorial issue in get_time (streambuf_iterator instead of istreambuf_iterator).
[ Batavia (2009-05): ]
This appears to be an issue of presentation.
We agree with the proposed resolution. Move to Tentatively Ready.
Proposed resolution:
In 31.7.8 [ext.manip]/4 within function f replace the first line
template <class charT, class traits, class moneyT>
void f(basic_ios<charT, traits>& str, moneyT& mon, bool intl) {
typedef istreambuf_iterator<charT, traits> Iter;
...
In 31.7.8 [ext.manip]/5 remove the first template charT parameter:
template <class charT,class moneyT> unspecified put_money(const moneyT& mon, bool intl = false);
In 31.7.8 [ext.manip]/6 within function f replace the first line
template <class charT, class traits, class moneyT>
void f(basic_ios<charT, traits>& str, const moneyT& mon, bool intl) {
typedef ostreambuf_iterator<charT, traits> Iter;
...
In 31.7.8 [ext.manip]/8 within function f replace the first line
template <class charT, class traits>
void f(basic_ios<charT, traits>& str, struct tm *tmb, const charT *fmt) {
typedef istreambuf_iterator<charT, traits> Iter;
...
In 31.7.8 [ext.manip]/10 within function f replace the first line
template <class charT, class traits>
void f(basic_ios<charT, traits>& str, const struct tm *tmb, const charT *fmt) {
typedef ostreambuf_iterator<charT, traits> Iter;
...
In 31.7 [iostream.format], Header <iomanip> synopsis change:
template <class charT,class moneyT> T8 put_money(const moneyT& mon, bool intl = false);
