char *ustrncpy(char *dest, const char *src, int n);
DESCRIPTIONThis function is like ustrcpy() except that no more than `n' characters from `src' are copied into `dest'. If `src' is shorter than `n' characters, null characters are appended to `dest' as padding until `n' characters have been written.
Note that if `src' is longer than `n' characters, `dest' will not be null-terminated.
RETURN VALUEThe return value is the value of `dest'.
