Unfortunately, the resulting facet is non-conformant. For this simple test case:
#include <locale>
#include <cstdio>
#include <cstdlib>
template<class _CharT>
class my_numpunct : public std::numpunct<_CharT>
{
public:
typedef _CharT char_type;
explicit my_numpunct<_CharT>() : std::numpunct<_CharT>() { }
~my_numpunct () { }
protected:
virtual char_type do_decimal_point () const {
std::printf("Hello, my name is my_numpunct::do_decimal_point.\n");
return std::numpunct<_CharT>::do_decimal_point ();
}
virtual std::string do_grouping () const {
std::printf("Hello, my name is my_numpunct::do_grouping.\n");
return std::numpunct<_CharT>::do_grouping ();
}
};
int
main(int argc, char* argv[])
{
if (argc != 2) {
std::fprintf(stderr, "Usage: %s <locale-name>\n", argv[0]);
return -1;
}
std::locale l(argv[1]);
std::locale loc(l, new my_numpunct<char> ());
my_numpunct<char> const& fac =
std::use_facet<my_numpunct<char> > (loc);
char dp = fac.decimal_point();
char ts = fac.thousands_sep();
std::string gr = fac.grouping();
std::string tn = fac.truename();
std::fprintf(stderr, "dp = '%c' ts = '%c' gr = \"%s\" tn = \"%s\"\n",
dp, ts, gr.c_str(), tn.c_str());
return 0;
}
I expect the following output:
[steleman@darthvader][/src/steleman/programming/stdcxx-ss122/stdcxx-4.2.1/tests/localization][09/15/2012
1:44:35][1134]>> ./22.locale.numpunct.stefan-1-gcc en_US.utf-8
Hello, my name is my_numpunct::do_decimal_point.
Hello, my name is my_numpunct::do_grouping.
dp = '.' ts = ',' gr = "" tn = "true"
I get this instead:
[steleman@darthvader][/src/steleman/programming/stdcxx-intel/stdcxx-4.2.1-thread-safe/build/tests][09/14/2012
22:31:22][1449]>> ./22.locale.numpunct.stefan-1 en_US.utf-8
dp = '.' ts = ',' gr = "" tn = "true"
