'man strncpy' on a recent Linux box contains:

DESCRIPTION
        The  strcpy() function copies the string pointed to by src 
(including the terminating ‘\0' character) to the array pointed to by
        dest.  The strings may not overlap, and the destination string 
dest must be large enough to receive the copy.

        The strncpy() function is similar, except that not more than n 
bytes of src are copied. Thus, if there is no null byte among the
        first n bytes of src, the result will not be null-terminated.

        In the case where the length of src is less than that of n, the 
remainder of dest will be padded with nulls.
