NAME

std::wcscat - std::wcscat

Synopsis

Defined in header <cwchar>
wchar_t *wcscat( wchar_t *dest, const wchar_t *src );

Appends a copy of the wide string pointed to by src to the end of the wide string
pointed to by dest. The wide character src[0] replaces the null terminator at the
end of dest. The resulting wide string is null-terminated.

The behavior is undefined if the destination array is not large enough for the
contents of both str and dest and the terminating null wide character.

The behavior is undefined if the strings overlap.

Parameters

dest - pointer to the null-terminated wide string to append to
src - pointer to the null-terminated wide string to copy from

Return value

Returns a copy of dest

Example

// Run this code

#include <iostream>
#include <cwchar>
#include <clocale>

int main(void)
{
wchar_t str[50] = L"Земля, прощай.";
std::wcscat(str, L" ");
std::wcscat(str, L"В добрый путь.");

std::setlocale(LC_ALL, "en_US.utf8");
std::wcout.imbue(std::locale("en_US.utf8"));
std::wcout << str << '\n';
}

Possible output:

Земля, прощай. В добрый путь.
