char *ustrncat(char *dest, const char *src, int n);
This function is like ustrcat() except that no more than `n' characters
from `src' are appended to the end of `dest'. If the terminating null
character in `src' is reached before `n' characters have been written, the
null character is copied, but no other characters are written. If `n'
characters are written before a terminating null is encountered, the
function appends its own null character to `dest', so that `n+1' characters
are written. You should try to avoid this function because it is very
easy to overflow the destination buffer. Use ustrzncat instead.
The return value is the value of `dest'.
