std::wcsncat

Header: <cwchar>

Appends at most count wide characters from the wide string pointed to by src to the end of the character string pointed to by dest, stopping if the null terminator is copied. The wide character src[0] replaces the null terminator at the end of dest. The null terminator is always appended in the end (so the maximum number of wide characters the function may write is count + 1).

# Declarations

wchar_t* wcsncat( wchar_t* dest, const wchar_t* src, std::size_t count );

# Parameters

dest: pointer to the null-terminated wide string to append to
src: pointer to the null-terminated wide string to copy from
count: maximum number of wide characters to copy

# Return value

dest

# Example

#include <clocale>
#include <cwchar> 
#include <iostream>
 
int main(void) 
{
    wchar_t str[50] = L"Земля, прощай.";
    std::wcsncat(str, L" ", 1);
    std::wcsncat(str, L"В добрый путь.", 8); // only append the first 8 wide chars
 
    std::setlocale(LC_ALL, "en_US.utf8");
    std::wcout.imbue(std::locale("en_US.utf8"));
    std::wcout << str << '\n';
}
