Description

Example

#include <iostream>
#include <cstdlib>

int main() {
    using namespace std;

    char* cpMultibyteChar       = new char[MB_CUR_MAX + 1];
    wchar_t wWideChar       = L'X';

    int iMultbyteChars      = wctomb(cpMultibyteChar, wWideChar);
    int iLength         = mblen(cpMultibyteChar, MB_CUR_MAX);
    // Add null-terminator
    cpMultibyteChar[iLength]    = 0;

    cout << cpMultibyteChar << endl;
    cout << iLength << endl;
    cout << iMultbyteChars << endl;

    delete [] cpMultibyteChar;

    return 0;
