wcsncat - concatenate two wide character strings

Syntax	#include <wchar.h> wchar_t *wcsncat(wchar_t *ws1, const wchar_t *ws2, size_t n);
Description	wcsncat() appends a maximum of n characters of the wide character string ws2 to the end of the wide character string ws1 and returns a pointer to ws1. The terminating null wide character code (\0) at the end of the wide character string ws1 is overwritten by the first byte of the wide character string ws2. If the wide character string ws2 contains less than n characters, only the characters in ws2 will be appended to ws1, and if ws2 contains more than n characters, then only the leading n characters of ws2 will be appended to ws1. wcsncat() terminates the wide character string with a null wide character code (\0).
Return val. Notes	Pointer to the resulting wide character string ws1. Wide character strings terminated with a null wide character code (\0) are expected as arguments. wcsncat() does not verify whether ws1 has enough space to accommodate the result. The behavior is undefined if memory areas overlap. Restriction This version of the C runtime system only supports 1-byte characters as wide character codes. They are of type wchar_t (see stddef.h).
