Concatenate two wide-character strings, up to a maximum length
#include <wchar.h> wchar_t * wcsncat( wchar_t * ws1, const wchar_t * ws2 size_t n );
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The wcsncat() function appends a copy of the string pointed to by ws2, including the terminating NUL wide character, to the end of the string pointed to by ws1. The first character of ws2 overwrites the NUL wide character at the end of ws1. The function writes no more than n wide characters from ws2 and appends a NUL wide character to the result.
The same pointer as ws1.
