Defined in header <cwchar> | ||
wchar_t* wcsncat(wchar_t* dest,constwchar_t* src,std::size_t count); | ||
Appends at mostcount wide characters from the wide string pointed to bysrc to the end of the character string pointed to bydest, stopping if the null terminator is copied. The wide charactersrc[0] replaces the null terminator at the end ofdest. The null terminator is always appended in the end (so the maximum number of wide characters the function may write iscount+1).
The behavior is undefined if the destination array is not large enough for the contents of bothsrc anddest and the terminating null wide character.
The behavior is undefined if the strings overlap.

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