wcsncat - Concatenate two wide character substrings

Definition	#include <wchar.h> wchar_t *wcsncat(wchar_t *ws1, const wchar_t *ws2, size_t n); 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 null wide character (\0) at the end of the wide character string ws1 is overwritten by the first character 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 byte (\0).
Return val.	Pointer to the resulting wide character string ws1.
Notes	This version of the C runtime system only supports one-byte characters as wide character codes. Wide character strings terminated with the null wide character (\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.
