strndup
Duplicates the first @n bytes of a string, returning a newly-allocated buffer @n + 1 bytes long which will always be nul-terminated. If @str is less than @n bytes long the buffer is padded with nuls. If @str is NULL it returns NULL.
To copy a number of characters from a UTF-8 encoded string, use func@GLib.utf8_strncpy instead.
Return
a newly-allocated buffer containing the first @n bytes of @str
