std::messages<CharT>::close, std::messages<CharT>::do_close

Header: <locale>

Public member function, calls the protected virtual member function do_close of the most derived class.

# Declarations

public:
void close( catalog c ) const;

protected:
virtual void do_close( catalog c ) const;

# 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

#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);
}
