public: void close( catalog c ) const; | (1) | |
protected: virtual void do_close( catalog c ) const; | (2) |
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.
#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);
}Output:
"No match" in German: Keine Übereinstimmung "Memory exhausted" in German: Speicher erschöpft
