NAME¶

std::messages::close,std::messages::do_close - std::messages::close,std::messages::do_close

Synopsis¶

Defined in header <locale>
public: (1)
void close( catalog c ) const;
protected: (2)
virtual void do_close( catalog c ) const;

1) Public member function, calls the protected virtual member function do_close of
the most derived class.
2) Releases the implementation-defined resources associated with an open catalog
that is designated by the value c of type catalog (inherited from
std::messages_base), which was obtained from open().

Parameters¶

c - a valid open catalog identifier, on which close() has not yet been called

Return value¶

(none)

Notes¶

On POSIX systems, this function call usually translates to a call to catclose(). In
GNU libstdc++, which is implemented in terms of GNU gettext(), it does nothing.

Example¶

The following example demonstrated retrieval of messages: on a typical GNU/Linux
system it reads from /usr/share/locale/de/LC_MESSAGES/sed.mo.

// Run this code

#include <iostream>
#include <locale>

int main()
{
std::locale loc("de_DE.utf8");
std::cout.imbue(loc);
auto& facet = std::use_facet<std::messages<char>>(loc);
auto cat = facet.open("sed", loc);
if (cat < 0)
std::cout << "Could not open german \"sed\" message catalog\n";
else
std::cout << "\"No match\" in German: "
<< facet.get(cat, 0, 0, "No match") << '\n'
<< "\"Memory exhausted\" in German: "
<< facet.get(cat, 0, 0, "Memory exhausted") << '\n';
facet.close(cat);
}

Possible output:¶

"No match" in German: Keine Übereinstimmung
"Memory exhausted" in German: Speicher erschöpft
