====== strncat ======

<code c>
#include <stdlib.h>
    char *strncat(char *dest, const char *src, size_t n);
</code>
appends the ''src'' string to the ''dest'' string, overwriting
the null byte ('\0') at the end of ''dest'', and then adds a terminating null
byte. The strings may not overlap, and the ''dest'' string must have enough space for the result.
